World’s Worst Lead Sites 1970s Bunker Hill Smelter – Idaho USA 1973-75

Smelter Kosovo, Yugoslavia 1972-1975

Broken Hill Smelter – Kabwe, Zambia 1972-75

Thousands of children poisoned in surrounding areas Blood lead levels 40-200 ug/dl Some mortality, several comatose in Kabwe, extensive

CNS / brain damage All coincided with high lead price in 1970’s

Lead Consumption 2010

1. Primary lead smelting has moved from the West to China 2. Primary lead demand is fueled by “new” uses -primarily vehicle growth as

new vehicles need new lead 3. Lead recycling is essentially a closed loop and cannot address growth 4. Forecast mined lead output will not keep pace with new lead demand

resulting in supply deficits 5. Very little new mine production is coming on-stream post 2010 6. Combination of limited lead concentrate availability and excess smelting

capacity in China will increase competition for concentrates and keep TC’s low

7. So will primary lead production survive in the recycling era? Unequivocally YES!

Summary of Primary Lead Smelting Industry Perspective

Summary of Mining and Primary Smelting Health and Environment Perspective

Mining – controlled in Developed Countries; varied in Middle Income countries; lax in Poor Countries

Primary Smelting – Leaving Developed Countries; varied in Middle Income Countries; absent in Poor Countries; most in China

Conclusions

Mineral Exploitation will Continue at an Exponential Rate

Lower Grade Ores and Wastes will become more Valuable

Developed Countries are Exporting their Pollution

Middle Income Countries are Incentivized to Lower Standards to Attract Business

Poor Countries are Desperate to Undertake Severe and Dangerous Practices to Mine and Recover Wastes

TerraGraphics International Foundation, Inc. Assistance to communities to reduce environmental exposures

Economic Incentives

Developed Countries Export the Pollution Problems Hope that Product Prices Don’t Increase

Middle Income Countries Compromise Standards to Compete for Business Adopt Lower Standards to Decrease Costs

Poor Income Countries Desperate for Any Income No Standards and Corruption

Last Word

The Prognosis is for Evermore Horrific Mining and Informal Recycling Related Environmental Health Catastrophes in Poor Countries

Middle Income Countries will Face Increasing Pressure to Compromise their Health, Environment and Worker Protection to Attract Mineral Processing Business

Developed Countries will Export their Environmental Health Problems to Avoid Compliance Costs and Lower Commodity Prices
