The International Previous Metals Institute selected Juan Francisco Medina, an MS student of Dr. Miller’s, for its annual Student Award for his work to improve flotation recov-ery of gold and silver from complex sulfide ores. He gets $3,500 plus travel expenses to IPMI’s annual meeting in Phoe-nix, June 2008.
Jun Lu received a Silver 2008 Materials Research Soci-ety Graduate Student Award for his PhD work under Dr. Fang on potential and reaction mechanism of the Li-Mg-Al-N-H system for reversible hydrogen storage. This includes $200, the meeting registration fee, and a one-year MRS student member-ship. In May 2007, Jun got The Excellent Chinese Graduate Student Studying Abroad Award from the Scholarship Council of the Ministry of Education of China, which has a prize of $5,000.
Nishant Tikekar (PhD 2007) received the Graduate Seminar Award for Best Stu-dent Presentation. Nishant scored 93.8% for his seminar, "Novel Double-Layer Titanium Boride (TiB2 + TiB) Coatings on Ti-6Al-4V and CP-Ti Substrates," presented October 11, 2006. Listen-ers praised his knowledge of math and the good match between his re-sults and theory, and said he an-swered queries confidently. His Ph.D. dissertation under Dr. Chandran re-ceived its final approval November 2007. From Mumbai, India, Nishant received his B.E. from Visvesvaraya Regional College of Engineering, Nagpur, India, and an M.S. in Material Science & Engineering from the U.

Are You Statisticking On Your Job? By Raj K. Rajamani
Hello, folks. Some of you may remember Mineral Processing III Statistics with John Herbst. Those were the days of the Hewlett Packard calculator-computer: a 3”-high rec-tangular flat box located upstairs in the an-cient pilot plant.
I belonged to a class of PhD and under-graduate students alike, and we were all, to say the least, a bit overwhelmed. We would trudge up a couple flights of stairs to do the lab. I remember inserting a 2” by 10” flat magnetic tape, a slender credit-card-looking thing, into the machine several times until it said “Ok, I am ready.” Then, it would spit out a five-foot-long paper receipt with all the multiple linear regression results. We would then have to browse through this spectacu-lar list and identify the correct numbers to complete the hypothesis tests. Oh my, that lab was quite the technical excursion for my
bewildered Met E 569 class and me. Prof. Herbst, being the compassionate
man he is, would of course give us a linear regression problem on the final exam. This required each and every one of us to use the flat box calculator, and let us kindly re-member that the ratio of students to the calculator was 20:1. So, on the day of the final, as if we were trying to score tickets for the very last Beatles concert, we would wait in a line stretching around the corner to the next corridor in order to get time on that godforsaken calculator-computer. Well folks, the times have changed.
Welcome to 2007 Statistics at the well-insulated Marriot Library PC lab, where the availability of a calculator-computer is the least of your concerns. There are 35 PCs with swivel chairs specially designed for students to be able to swing left or right to glance at the screen. The roles have re-versed; I am now the instructor, and as op-posed to the days of monotonous chalk-board writing, I can project my PC onto a large screen. It doesn’t matter if there are
1000 or 100,000 data points, you need only click the mouse once, and the lab is com-plete. Nowadays, all that I can possibly ask on an exam appears on the screen, so the crucial question becomes, “How do I chal-lenge the students?”
Our departmental statistics class has gained a lot of ground within the College of Mines and Earth Sciences in the last ten years. It is offered for all departments within the college. In 2007 around 35 students took the course. Lately, a few bioengineer-ing students have been registering for our class. The word is finally out, folks, this class is much more meaningful than a raw statistics course in the Math department. It provides a specialized statistics course for students in the engineering field.
So as far as the statisticking goes, for all you engineers, are you checking for normal-ity at the end of the day? And, more impor-tantly are you satisfying the assumptions of statistical theory? I hope so, and I also hope you are enjoying the new-age technology that makes it so easy to do so.

Dr. Mohamed Ismail Al-Wakeel, Assoc. Prof. of Geology, Faculty of Science, Ain-Shams Univ., Cairo, Egypt, came in August as a Visiting Re-searcher on a postdoctorate scholarship. He worked on characterization of nonsulfide mineral resources, including Egyptian diatomite and Flor-ida phosphate resources. Characterization tech-niques include XRD, X-ray computed tomogra-phy, and optical polarizing microscope. Results of the research were presented at the SME Annual Meeting in February 2008 in Salt Lake City.
Dr. Birgül Benli was a visiting scholar July 2007 to February 2008, supported by the Scien-tific and Technical Research Council of Turkey for the BIDEB-2219. She is on the staff of the Chemi-cal & Metallurgical Eng. Dept. at Istanbul Techni-cal Univ., Turkey. Her research investigated the interactions between clay minerals and biode-
gradable alginate using atomic force microscopy. The results will be useful in preparation of high-quality biodegradable composites.
Dr. Dee Bradshaw, Univ. of Cape Town, Re-public of South Africa, did research at KUCC’s Copperton Concentrator on assignment by Rio Tinto, and sabbatical leave from UCT, June–September. Collaboration includes research on sulfide flotation with grad student Luis Roman and discussion of X-ray tomography for mineral exposure/liberation analysis with Richard Beck, AMIRA, Emmy Manalapig and Malcolm Powell, JKMRC, and J.P. Franzidis, Univ. of Cape Town.
Dr. Fangqin Cheng and Yaning Zhang ar-rived at the end of June 2007 for a six-month assignment as Visiting Scholars supported by the China Scholarship Council, to do applied re-search on the influence of impurities, especially magnesium, on KCl flotation in plant practice surface chemistry of soluble salt flotation. They are from ShanXi Univ., Inst. of Environmental

Expanded X-ray CT Laboratory By Jan Miller and C. L. Lin
During the past seven years, our X-ray microcomputed tomography (micro-CT) in-strumentation has provided 3D visualization and analysis of multiphase systems at a res-olution of ten microns. This custom-designed system was the state of the art when ac-quired and has been used by researchers from many departments in both our college and the College of Engineering, and has supported many industrial research projects.
The past success of our cone-beam X-ray micro-CT lab is quite evident, but in view of recent advances improving resolution, new facilities are required in order to maintain a state-of-the-art position in the area of proc-ess tomography. In this regard, expansion of the lab is planned to include X-ray milli-, micro-, and nano-CT facilities for 3D multi-scale imaging of multiphase systems.
This quantum step forward in 3D visuali-zation of multiphase systems will have many applications in the mineral industry, such as analysis of drill core exploration samples, mineral liberation/exposure analysis, pore structure characterization, crack formation/preferential grain boundary fracture, charac-terization of irregularly shaped particles, particle beds and of activated carbon sam-ples, analysis of leaching reaction progress, and use as an important optimization tool for mine planning/plant operation.
Our expanded lab’s utility will be similarly realized for the materials industry with re-spect to composites, electronic materials, construction materials, MEMS, and the new areas of nano and bio materials. Characteri-zation of construction materials, for example, will allow detailed analysis of mechanical, thermal, and acoustical properties of multi-phase materials with complex geometry.
The first step in this expansion is acquisi-tion of the latest high-resolution X-ray mi-cro-CT system, for around $600,000. This system will extend our resolution by more than an order of magnitude, from 10 microns into even the submicron (500 nm) region. We’ve received university and industry sup-port and are now preparing a proposal. The successful acquisition of the high-resolution X-ray micro-CT system will be followed later in 2008 with an initiative to acquire an X-ray nano-CT system having a resolution at 50 nm, at ~$1M.
Communition Research By Raj K. Rajamani
In the ‘60s and ‘70s, Bond work index ruled. I like to believe that selection func-tions and breakage functions ruled the ‘80s and ‘90s. That was just an expansion from one size to ten size intervals.
But let me tell you what happened since the ‘90s. It became possible to depict each ball and each rock particle as spheres. Now things can be explained in a simple three-step process: First, draw the volume outline of the mill with all the lifters and other com-ponents in an AutoCad package. Then throw in the hundreds of thousands of spheres, and spin the mill at 10 rpm.
When we did this, it took approximately five days on a PC for two full revolutions. As opposed to the days when nothing could be said about impact force, the outcome is that now I can tell you the result of the impact force on each rock particle and furthermore
say something about the entire population of rock particles within the mill. Imagine that!
My student B.K. Mishra (PhD 1991) de-veloped this methodology. Mark Sherman and I were the first to apply it to a SAG mill at the Alumbrera Mines in Argentina. That project was a fabulous triple success for mill concentrator production.
Guess what happened next? The popula-tion balance model, as of today, is on the verge of extinction. Researchers at major institutions, including myself, are engaged in converting the impact spectra into ore breakage. One day it will be possible to tell the exact size distribution at every nook and corner of the SAG mill. That in brief is the current theme of my research. Today, re-search institutions, schools, and even cor-porations are investing large bundles of money and talent in the discrete element method for comminution. I hope to put this model on the market in a couple of years.

Characterization, Analysis, & Simulation of Multiphase Systems by Micro CT
One research program of considerable interest under Prof. Miller's supervision is on characterization, analysis, and simulation of multiphase systems by micro CT, led by Dr. Chen Luh Lin, Research Professor, and Alvaro Videla, PhD candidate, with partici-pation of other grad students Wenjing Xu, Phanindra Kodali, and Ken Hsieh.
This exciting research has projects in progress on exposure/liberation analysis of multiphase particles, fracture phenomena occurring during particle breakage in high-pressure grinding rolls, conditions for prefer-ential grain-boundary fracture and fracture propagation, transport phenomena of satu-rated and two-phase flow in porous media, and spatial analysis of phase boundaries.
Study of these multiphase systems in-volves, among other methods, use of X-ray micro-CT (XMT) for 3D digitized imaging, the Lattice-Boltzmann method for 3D fluid-flow simulation in complex geometries, simulation and modeling of particle packing structures, development of image analysis software for particle identification in packed
particle beds, and micro finite-element analysis for strength/fracture evaluation.
The most significant achievements in recent years include development of nonin-vasive, nondestructive 3D particle analysis techniques, where multiphase composition and liberation analysis of ore samples can be accomplished using XMT and 3D image data analysis. Notable applications with our industrial partners have been reported for wallboard analysis, copper ore exposure/liberation analysis, and liberation limitations in phosphate flotation recovery.
Recently, Daniel Garcia finished his M.S. thesis determining what conditions preferential fracture occurs under. His work involved quantitative analysis of fracture patterns and determination of the extent to which interfacial area is conserved after particle breakage.
An ongoing area of research involves the 3D simulation of multiphase flow in porous media, based on Lattice-Boltzmann meth-ods. Preliminary results that have been re-ported included calculation of hydraulic con-ductivities for saturated and unsaturated packed particle beds, percolation, fingering, and fluid displacement.

In the vibrational spectroscopy labora-tory, under Prof. Miller’s supervision, Dr. Jin Liu is responsible for the Fourier transform infrared (FTIR) spectroscopy and sum-frequency vibrational spectroscopy (SFVS) instruments. Vibrational spectroscopy pro-vides the most definitive means for identify-ing the nature of surface species and ad-sorbed states in aqueous systems.
In 2007 we applied the SFVS technique to study molecular features of soluble car-bonate salts at the air/carbonate solution interface. Currently, we are investigating the
adsorption characteristics and interfacial water structure of other soluble salts . A new research effort is planned using in-situ FTIR techniques to study the interfacial chemistry dynamics of surfactants and wa-ter-soluble polymers under high-shear con-ditions. Most previous research on surfac-tant adsorption states and interaction with colloidal particles focused on static systems, without considering the behavior of the sur-factants/polymers under external force fields such as shear flow. Successful design and evaluation of the rotational FTIR internal reflection element will let us study dynamic interfacial phenomena in-situ.
Molecular Dynamics Simulation Hao Du initiated research on surface/
interfacial chemistry using molecular dy-namics simulation (MDS). The study exam-ined in detail water structure and dynamics at selected alkali halide salt crystal surfaces and addressed the significance of interfacial water structure for the collector surfactant adsorption states at these surfaces.
Sodium carbonate and bicarbonate brine solution surface tensions were calculated using data collected from MDS. Comparison with experimental results provided comple-mentary information on the water structure making and breaking characteristics of car-bonate and bicarbonate ions.
We made significant progress in under-standing the surface chemistry of some naturally hydrophobic mineral surfaces. The
surface properties of talc basal plane, graphite, and sulfur surfaces were studied by examination of in-terfacial water structures. The ad-sorption states of amphipatic solutes such as cationic amine surfactant and dextrin molecules at these sur-faces were simulated. Mineral sur-face hydrophobicity, nanorough-ness, and lattice polarity all seem to influence surfactant adsorption at naturally hydrophobic mineral sur-faces. It is evident that MDS pro-vides another important tool for the analysis of interfacial chemistry, and its use continues in the study of water structure to complement SFVS, NMR, and neutron diffraction experiments.
Hao successfully defended his thesis on 1 August 2007.

Electro- & Hydrometallurgy by Prof. Mike Free
My group has started some exciting new corrosion research to understand the effects of thermal cycling on aluminum alloy corro-sion in naval applications. We are collabo-rating with other universities and the Naval Research Labs to develop a more compre-hensive understanding of these effects in order to minimize future corrosion. We re-cently initiated research to develop vapor-phase corrosion measurement techniques for aerosol spray cans used for common retail products. Other projects include work for the copper industry to improve leaching performance as well as electrowinning tank-house monitoring techniques.
We recently began a project with Prof. Jack Adams to recover gold with the assis-tance of microorganisms. We welcomed three new grad students, Prashant Sarswat, Shamita Shitole, and Soumya Kar, and an undergraduate, Alysha Com-stock, into our group this year. Our work in corrosion was recognized this year with a 2007 Literati Award from the journal Anti-Corrosion Methods and Materials, in con-nection with a recent publication. Prof. Free recently traveled to China to establish more international research connections.
Electrocatalysts, Copper & Gold Processing
2007 was a very productive year for Prof. Mike Moats and his research group, which has grown to include four graduate re-searchers, Francis Elnathan, Priyank Gupta, Chayata Piriyapong, and Prachi Shrivastava, and an undergrad researcher, Richard Cutler, working on projects funded by DOE/CAST, Freeport McMoRan, Kenne-cott Utah Copper, and the Petroleum Re-search Fund. These focus on coated tita-nium anodes, solvent extraction of gold, and fuel cell electrocatalysts for alternative re-newable fuels.
Mike coauthored seven papers in 2007 on electrocatalytic coatings for industrial electrolysis, anode passivation in copper electrorefining, industrial surveys of copper electrowinning and electrorefining, and the future of copper electrowinning.
As shown by the paper topics, Dr. Moats has been heavily involved with the copper industry. In April, he was voted to be the coordinator for the Copper Refining Group, a North American industry consortium of all operating copper refineries. Mike replaces John Dutrizac of CANMET as coordinator.
In August 2007, Dr. Moats was very ac-tive with Copper 2007. He was one of the instructors of the short course Fundamen-tals and Practice of Copper Electrorefining
and Electrowinning, chaired two technical sessions and delivered two papers. Finally, during the year, Mike assisted two copper production facilities in improving their opera-tions.

Steel Processing Dr. Weol Cho is focusing on two pro-
jects related to steel processing. Recently, a new synthetic oxide flux system based on titanium oxide was developed to remove nitrogen from molten steel. The new oxide is much more effective than any oxides studied previously. The research results were published in Metallurgical & Materials Transactions B. Research to apply the ox-ide to stainless steel to control nitrogen content is continuing.
The other project is to develop a new process to eliminate copper impurity from solid ferrous scrap, in particular auto scrap. A trace amount of copper has a detrimental effect on various steel properties, and thus ferrous scrap containing copper has not been recycled effectively by the steel in-dustry, especially the EAF minimill industry. The proposed process removes copper without melting scrap, unlike processes attempted previously. Fundamental lab-scale studies are underway to fully develop the technology.

There’s a story often told regarding the width of train tracks. After following the history back through trams, wagon wheels, wheel ruts in old Roman roads, and Roman chariots, it summarizes, “The United States standard railroad gauge of 4 feet, 8.5 inches derives from the original specification for an Imperial Roman war chariot. Specifications and bu-reaucracies live forever. So the next time you are handed a specification and wonder what horse's ass came up with it, you may be ex-actly right, because the Imperial Roman war chariots were made just wide enough to ac-commodate the back ends of two war horses.”
Sometimes the tale continues, “Now the twist to the story... When we see a Space Shuttle sitting on its launch pad, there are two big booster rockets attached to the sides of the main fuel tank. These are solid rocket boosters, or SRBs. The SRBs are made by Thiokol at their factory at Utah. The engineers who designed the SRBs might have preferred to make them a bit fatter, but the SRBs had to be shipped by train from the factory to the launch site. The railroad line from the factory had to run through a tunnel in the mountains. The SRBs had to fit through that tunnel. The tunnel is slightly wider than the railroad track, and the railroad track is about as wide as two horses' behinds. So, the major design feature of what is arguably the world's most advanced transportation system was determined over two thousand years ago by the width of a horse's ass!”
(You can read the complete story at http://god-101.blogspot.com/2008/03/horses-ass.html — one of the few sites that gives an author, Allan W. Janssen.)
An alum, Howard McIntosh, was sent the story by his son-in-law, with the question — Is this really true about the space shuttle solid rocket boosters? Howard had been in charge of the design and material procurement for the boosters at Thiokol, so his son-in-law knew he would know the real story.
Here’s Howard’s version of how it came about — straight from the horse’s mouth.
* * *
Hi John, Quite a story! But not quite right – close but not quite. Here is the real story. We did a lot of preliminary work on the boosters and found 156-inch diameter case gave a good performance as test motors. It came down to making a reusable high-strength, half-inch wall, rocket motor case without welds, since weld material is subject to defects and fatigue cracking. The booster cases had to survive multiple recovery splashdowns of hit-ting the water at 60 miles per hour. We figured that the highest loads occurred on a calm day with a smooth ocean surface and were caused by the 'cannon ball effect' when the cavity collapse produced a water hammer effect after impact. The cases were to be ca-pable of a minimum of 20 cycles of refurbish-ment.
The only company capable of forming large seamless high-strength steel cylinders was Ladish Company in Milwaukee. Their biggest thin-walled cylinders were 120 inches in di-ameter for the Titan boosters. So I gave them a research contract to determine the largest diameter they could form, and we came up with 146-inch maximum because of equip-ment and tooling restrictions. In fact we had to remove guards and shields in places to achieve that.
So the diameter was set by beyond-the-state-of-the-art tooling capabilities and not by the width of the railroad. We had transported motors as large as 260 inches in diameter around the country. We did have to pick out the best routes to ship the SRB's from Utah to Florida and the cases back to Utah to avoid any restrictions but that was for convenience and long-term efficiency. Quite a story isn't it? But that's the real story from the other end of the horse.
Thanks for asking. Love to you and yours, Howard

A new NSF-funded study attempts to exploit the anomalous diffusion near phase transition for achieving deep surface hardening of metals. Recently, it was observed that large ingress of boron and rapid growth of the TiB layer occurred when diffusion was performed very close to poly-morphic transition temperature of titanium. This research is exciting, since, although the mechanism of diffusion near transition temperatures of hcp metals was known to be anomalous, it had not been exploited to achieve deep surface hardening of hcp metals such as titanium.

In Memoriam
Phillip DeLance Chase died at home in Bountiful, Utah, on July 9, 2007 after an extended illness. He was born February 26, 1935 to Phillip Thorn and Virginia Bishop Chase in Salt Lake City, the eldest of four. He attended both BYU and the U.
For most of his life, Phil worked in the metallurgy lab on Hill Air Force Base, alongside his younger brother David. An elaborate practical joker with a keen sense of humor, Phil alternately entertained and terrorized co-workers (abetted by "Little Brother") for more than 30 years until he retired in 1999.
Phil served an LDS mission in Guate-mala from 1954 to 1956 and on June 26th, 1959, married his high school sweetheart, Jane Briggs Bowen. Phil and Jane lived for a time in Southern California before settling in Bountiful in 1966. They raised four chil-dren and remained happily married for more than 47 years. Jane lost a long battle with breast cancer in January 2007.
Phil had a special love of Scouting and Young Men's programs. He served in two bishoprics as well as numerous ward and stake assignments, including (to the cha-grin of some) editor of the ward paper for many years.
He was the unofficial poet laureate to a wide circle of family and friends, creating original (and hilariously irreverent) verse to mark every occasion in life – from birthdays and anniversaries to a particularly satisfy-ing racquetball victory.
Phil was a great lover of nature and the outdoors, interests he inherited from his own father. He was an avid bird-watcher and loved to camp, hike, swim, and go river rafting; passions he shared with his whole family, especially his three boys — all of whom followed his footsteps into scouting, but none of whom equaled his skills, enthu-siasm and commitment. Phil was also a skilled carpenter and handyman, talents he shared generously with family and friends.
Phil is survived by his four children, Karl (Bountiful); Kevin (Los Angeles); and Ste-ven Chase (Bountiful); and Wendy Chase Arnold (Joseph G.

Alan Everett Isaacson (BS 1983) 1961-2008
Alan Everett Isaacson died March 31, 2008, while on a week-end camping trip.
He was born September 12, 1961 to Everett "Mick" and Bonne H. Isaacson in Salt Lake City. He attended Glendale Ele-mentary, Churchill Jr High, and Skyline High School.
Alan worked for the Bureau of Mines before returning to the U for an M.B.A. de-gree. He then worked for the Utah Bureau of Economic and Business Research.
Alan was happiest in the outdoors and spent much of his free time hiking, fishing,
and camping. He had recently developed an interest in travel, especially to Central Amer-ica, and greatly enjoyed touring those coun-tries.
Alan was close to his large extended family of uncles, aunts, and cousins. He is preceded in death by his parents and sur-vived by brother Mark J. Isaacson, sister-in-law Alice H. Isaacson, and niece and nephew Nicole and Matthew.
Rex Lamar Outzen passed away Friday, December 14, 2007 at the age of 54. Rex was born on Novem-ber 4, 1953 in Tooele, Utah to Sand ra and Richard Outzen. He was very athletic and was a three-sport letterman in basketball, baseball and football at Tooele High and graduated in 1972. He continued his edu-cation at the University of Utah.
He believed in working hard and making something of yourself; which led him to a successful career in the precious metals mining industry. His career took him around the world, moving from one project to the next, but he always considered Tooele his home. Several years ago he moved back to Utah and built a home in West Jordan. He was an avid sportsman and enjoyed hunt-ing and trap shooting around the country. He even took a crack at retirement a few years ago and opened the Great Salt Lake Gun Club with a partner. However the min-ing industry called, and he could not resist returning to his career.
Rex was preceded in death by his grand-parents, Wallace and Aileen Outzen, and his father Richard Outzen. He is survived by his wife Angela, mother Sandra, son Craig, daughter Angie, the mother of his only grandchild, Xavier Lopez, brother Ty (Monique), sisters Pattie and Brenda, and niece and nephews Tyra, Taz and Marc.
Rex Lamar Outzen (BS 1977) 11/4/1953– 12/14/2007 Jerry Lee Huiatt died in March 2004. He
received his BS in 1957 from Colorado State University and worked at Shell Chemical, the Denver Water Board, and the U.S. Bureau of Mines.
Jerry Lee Huiatt (MS 1969) March 2004
Val Ness was born in Chile on June 5, 1922, and died July 21, 2007. He resided in Highlands Ranch, Colorado.
He was the husband of Terri, father of Matthew (Molly) Ness and Rebecca (Waheed) Choudhry, grandfather of Ava Marie and Ella Rae Choudhry, and brother of AnnaMarie Robb and Valerie Ness. He was also survived by his loving companion, his dog Spike.
