1.0 EXECUTIVE SUMMARY:

Nadidih Iron & Manganese Mine, covering an area of 121.405 ha of M/s

Feegrade & Co. (P) Ltd. is in operation since 1961. The site is at a distance of

25km from Barbil and is well connected by an all-weather metal road. In

pursuance to section 8-A (6) of MMDR Amendment Act, 2015, the mining lease

period has been extended up to 31/03/2020 by execution of a Supplementary

Lease Deed on 02.05.2015 over an area of 121.405 hectares. The lease area of

121.405 ha comprises 89.870 ha of forest land (PF+KF+DLC) and 31.535 ha of

non-forest land. Stage-II Forest clearance for an area of 39.309 ha has been

accorded by MoEF, Govt. of India vide letter no. 8(21)26/2003-FCE dated 16

/03/2006 and 45.118 ha of additional forest & deemed DLC forest land for

mining and allied activities (including 8.036 ha of forest land for safety zone)

vide F. No. 8-68/2011-FC dt. 30/10/2013.The lessee had applied for surrender

of 5.443 ha forest land which is under process.

At present, the production of the mine is restricted to excavation of Iron ore

(ROM) from mine and dry screening & crushing of iron ore. These crushing &

screening produce processed ore of +55% and -55% Fe. The overall objective

of the project for grant of Environmental Clearance is to meet the following:

Increase in production of Iron Ore from 2.88 million TPA ROM Iron ore to 6.0

million TPA (ROM) and dry processing of iron ore of 1.451 million TPA. Total

handling will be 7.451 million TPA& 1.451 million TPA dry crushing/screening

of low grade ore from old stack/dumps. The mine was accorded Environmental

Clearance vide order no. J-11015/136/2012-IA.II (M) dated 10.04.2015 for

2.88 million TPA ROM and dry processing of 4.571 million TPA of low grade

iron reworking of old dumps thus total handling of 7.451 million TPA and

installation of wet beneficiation plant of 1.142 million TPA capacity and

production of 0.0036 million TPA of Manganese ore. Installation of wet

beneficiation plant of 1.142 million TPA capacity has been deleted by Ministry

of Environment, Forests and Climate Change vide letter no. J-

11015/136/2012-IA.II (M) dated 09.11.2015.



Total handling of iron ore will be 7.451 million TPA to get 5.90 million TPA

of processed iron ore of grade +55 % and balance of grade – 55 % (Refer

Exhibit No.1). The ROM, accumulated mineral rejects & wastes from

Nadidih Iron & Manganese Mines will be hauled through trucks/dumpers to

dry processing plants. After processing, the finished iron ore will be carried

to the Railway siding and loaded into Rail wagons and dispatched mainly to

the steel, pelletisation, sponge, sinter plants throughout India and also to

port for export. In the project, due care is taken for optimum use of

natural resources and their conservation and this will continue further. The

company has the electricity permission of total 213 KVA from WESCO, a

power holding company of State Govt. of Odisha. There are also 02

standby generators of total capacity 140 KVA for support.

There is a mine camp within the ML area having about 132 nos. of

residential quarters for its employees of different categories. The social

infrastructure adjacent to the project area includes a health centre and one

Primary School. As a part of CSR activities the Company has undertaken

the construction works of School buildings, boundary wall for Schools &

Temples, club houses in villages, digging of ponds in nearby villages and

bore wells. Such type of work will continue in future. The entire

infrastructure related facilities for traffic and transportation for the mine

are already available. So, there is no new proposal for the same.

The estimated project cost is Rs.200Crores. As regards the economic

viability of the project, this Iron & Manganese mine supplies iron ore to the

steel, pelletisation, sponge, sinter plants of India and also for Export. The

production cost is very favourable than the market price.

The per capita consumption of steel is increasing with the economic

development of people in the World. There is positive market demand of

steel at present and more production of steel is required to bridge the gap

between demand and supply to achieve sustainable development. Hence,



the capacity expansion of this mine will meet the urgency of iron ore in

domestic as well as international market. The State will also earn more

revenue from the increased iron ore production and can utilize in its

developmental plans. The capacity expansion plan will also create direct

and indirect employment opportunity for the local youths that will help to

minimize the unemployment problem as well as all around development of

the surrounding area.

Nadidih Iron & Manganese Mine over an area of 121.405 ha of M/s

Feegrade& Co. (P) Ltd. is under operation since 1961. Nadidih Iron &

Manganese Mine was operated manually in the beginning. But at present,

the mining operation is mechanized with production of 2.88 million TPA

ROM and dry processing of 4.571 million TPA of low grade iron reworking

of old dumps having total handling capacity of 7.451 million TPA and

production of Manganese ore of 0.0036 million TPA. At present, it is

proposed to increase the production capacity of the mine from 2.88 million

TPA of ROM iron ore to 6.0million TPA ROM iron ore and dry



crushing/screening of 1.451 million TPA for reworking of old dumps/stacks

for up gradation of low grade recovered from screening of ROM ore and dry

screening of low grade ore. There will be no change in total handling of

material which will be 7.451 million TPA and also there will be no change in

production quantity of Manganese. The ROM ore produced by the

excavation of quarry generally consisted of blue dust, lump iron ore, etc.

This iron ore will be produced by developing up to 9metre benches in the

quarry. The benches will be developed by using different mining

machineries like excavator, tippers, rock breakers, deep hole drilling &

blasting etc. After excavation, ROM iron ore will be processed through in-

pit mobile crushing & screening units.

2.1 Identification of Project & Project Proponent (in case of mining project, a copy of mining lease/letter of intent should be given) :

2.2 Brief description of nature of the project:

Nadidih Iron & Manganese Mine is an operating mine with a capacity to

produce2.88 million TPA ROM and dry processing of 4.571 million TPA of

low grade iron reworking of old dumps, total handling of 7.451 million TPA,

installation of wet beneficiation plant of 1.142 million TPA and production

of 0.0036 million TPA Manganese ore granted Environmental Clearance

vide order no. J-11015/136/2012-IA.II (M) dated 10.04.2015. Installation

of wet beneficiation plant 1.142 million TPA capacity has been deleted by

Ministry of Environment, Forests and Climate Change vide letter no. J-

11015/136/2012-IA.II (M) dated 09.11.2015.At present, the ROM ore

produced in the mine are subjected to dry crushing& screening. The

produced iron ore fines are exported as well as dispatched or sent to

domestic pelletisation/sinter plants. The sized ore are dispatched to

domestic market either through road or through Rail head. The lessee has

already got the necessary permissions from Govt. authorities to fulfill the

demand supply gap of iron ore. Now, it is proposed to enhance the

production of the mine from 2.88 million TPA ROM iron ore to 6.0 million

TPA ROM iron ore and dry processing which include crushing and screening

of low grade ore of 1.451 million TPA having total handling 7.451 million

TPA to get 5.90 million TPA of processed iron ore of grade +55 % and

balance of grade – 55 % Fe.

2.3 Need for the project and its importance to the country and the

region:

Due to market demand of iron ore for domestic steel, sponge and

pelletisation and sinter industry and to meet the export demand, the

project proponent wishes to increase the production capacity of iron ore of

the mines by handling of 7.451 million TPA iron ore i.e., 6.0 million TPA

ROM iron ore and dry crushing and screening of 1.451 million TPA from old

stacks/dumps ROM iron ore. The Govt. will earn more revenue and more

job opportunities will be created. Besides more indirect employment will be

generated through handling of material, transportation, etc. which will



result in economic improvement of the people in the locality. Many people,

apart from the above will get other avenues for livelihood, which will help,

in improving the economic and social status of the people in the area.

2.4 Demand-Supply Gap:

The Indian Steel industry has entered into new development stage from

2005-06, riding high on the resurgent economy and rising demand of steel.

Rapid rise in production has resulted India to become the 5th largest

producer of steel. It is estimated that, India’s steel consumption will

continue to grow at nearly 16% rate annually, fueled by the demand of

construction project. The National Steel Policy envisaged steel production

to reach 110 million tonnes by 2020. So, considering these huge demands

of iron ore for steel industries, the supply is not sufficient. So, this project

is important for partial fulfilling of demand.

2.5 Imports Vs. Indigenous Production:

To minimize the growing import of steel, it is necessary to increase the

indigenous production of steel in India. For this it is necessary to produce

more iron ore as raw material. The expansion of the project will partially

meet the demand of raw materials for our upcoming steel industry.

2.6 Export Possibilities:

China & Japan being the 1st& 2nd crude steel producers of World, depend

partly on India for iron ore as raw material. India is the 3rd largest iron ore

provider to China’s steel industry. So there is always an export possibility

of iron ore from this mine.

2.7 Domestic/Export markets:

The sized iron ore from this mine has demand in domestic steel & sponge

industry. During production of lump iron ore, fines of iron ore will be



generated automatically, this iron ore fines are exported to China as well

as supplied to domestic pelletisation/sinter plants.

2.8 Employment Generation (direct & indirect) due to the project: Manpower:

Existing& Proposed:

As in this mine total handling will remain same as 7.451 million TPA and

there is change in ROM production only there may by opportunity for direct

employment of total 426 people and indirect employment of 400 people.

So, 826 people will get engagement due to enhancement of the project.

Existing Proposed

Graduate Mining Engineer 2 2

Diploma Mining Engineer 1 1

Geologist 1 1

Surveyor 1 1

Other Officers 12 14

Mine worker for manual sorting &

Total 346 426

Besides direct employment, many more persons are benefited through

indirect employment as contract jobs, which are mainly extended to the

local tribes.

3.0 .PROJECT DESCRIPTION:

3.1 Type of project including interlinked and interdependent projects,

if any:

In Nadidih mine, ROM iron ore will be produced from the mine by

mechanized method of excavation of the quarry by excavator, tipper, deep

hole drilling, blasting, rock breakers, etc. ROM ore is further processed by

dry crushing, screening.

Location map showing general location, specific location and project

boundary is attached herewith as Plate No.1.

3.3 Details of alternate sites considered and the basis of selecting the

proposed site, particularly the environmental considerations gone

into should be highlighted:

It is already a running mine.

3.4 Size of magnitude of operation:

The project cost of Nadidih Iron & Manganese Mine is Rs200Crores. It

involves mining of ROM Iron ore, dry crushing & screening of ROM ore to

produce processed iron ore of + 55% and -55% Fe. The processed iron ore

will be produced by processing of excavated ROM iron ore& processing of

low grade iron ore and waste.

At present production capacity of the mine is 2.88 million TPA ROM iron ore

and dry processing of 4.571 million TPA of low grade iron reworking of old

dumps having total handling of 7.451 million TPA. After expansion ROM

production of the mine will increase from 2.88 million TPA ROM iron ore to

6.0 million TPA ROM iron ore and dry processing will reduce from 4.571

million TPA to 1.451 million TPA of low grade iron ore by reworking of old

dumps/stacks.



3.5 Project description with process details (a schematic diagram/flow

chart showing the project layout, components of the project, etc.

should be given):

The mining method of Nadidih Iron & Manganese Mine will be fully

mechanized to handle 7.451million TPA of iron ore to produce

5.90million TPA processed iron ore of + 55% grade. The conventional

opencast mining with mechanized drilling with 110mm dia drill machine,

deep hole blasting, excavation by excavator of capacity 2.6 m3bucket

capacity and stacking by loader of capacity 1.2 m3. Excavator of

capacity 1.6 m3 /1.5 m3 will be used for feeding the crushing &

screening unit. ROM iron ore will then be processed through dry

crushing &screening units. To prevent generation of fugitive dust during

transportation of ore through trucks/dumpers, static water sprinklers

have been installed along the haul road within the mine for a length of

5.04 km. Besides that water is also been sprinkled through water

tankers of different capacities.

3.6 Raw Material required along with estimated Quantity, likely

source, marketing area of final products, mode of Transport of

raw material & finished product.

It is a mining project to produce iron ore. Low grade iron ore from this

mine will be processed to get saleable ore. There is no need of any raw

material from outside agency.

Iron Ore is having a very good market in India & abroad. So after

production it is immediately saleable to beneficiation plant/sinter/ sponge

and steel industry present in Odisha, Jharkhand, M.P., Chhattisgarh and

other parts of India. China, Korea & Japan are the major buyers from

abroad.

Within the Mine both Iron Ore & Waste Materials will be transported

through tippers of capacity 20 MT. The sized Iron Ore and Fine are

transported to railway sidings at Barsuan, Rengra, Barbil, Bolani etc.

through Tippers of capacity 10 MT or 20 MT. From railway siding, Iron Ore



is transported to buyer’s destination or port by rake. Sometimes Iron Ore is

also supplied to the Seaport by trucks from the mines through road.

3.7 Resources optimization/recycling and reuse envisaged in the

project, if any, should be briefly outlined.

As discussed earlier the low grade ore will be crushed and screened for

optimal use of iron ore.

3.8 Availability of water its source, Energy/Power requirement and

source:

Water requirement:

In Nadidih Iron & Manganese Mine water is required for different

operational purpose and also for domestic purpose.

The water requirement as per EC accorded on 10.04.2015 is 2566.6

KLPD (Surface water 2340.38KLPD, Ground water 226.22 KLPD)

including 1599 KLPD for Wet Beneficiation plant. The water is sourced

from Karo River.

Since in the new proposal Beneficiation plant is not there the water

requirement is 993.5 KLPD only (surface water 767.5 KLPD, ground

water 226 KLPD). 520.06 KLPD approval for surface water &226 KLPD

approval for ground water is already there.

For drawl of balance surface water (247.44KLPD), is under process to

the concerned authority.

Energy power requirement:

The machineries will be operated either through electricity or through H.S.D.

details are given below.

(1) Electricity requirement: The electricity is supplied to the project by

WESCO through 2 nos. transformers of total capacity 213 KVA inside

leasehold. There is also requirement of transformers with total capacity

of 350 KVA.



(2) Details of Generator: 2 nos. of generators of total capacity 140 KVA

exist. There is a further requirement of generator of capacity 400 KVA.

(3) H.S.D. requirement: Present requirement of H.S.D is 1192006

Liters/year. For the envisaged increase in production total H.S.D.

requirement will be around2292000Liters/year.

3.9 Quantity of waste to be generated and scheme for their

management.

Solid Waste Management:

The waste materials of Nadidih Mines are mainly laterite, lateritic Iron

ore, BHQ, BHJ, shale, alluvial soil etc. Total 8300748 m3 of waste

material exists at present. It is expected that 2671588 m3 of waste will

be generated up to the end of the life of the mine. 309248 m3waste

materials of this mine will be dumped in and balance part of the waste

material will be used for backfilling of exhausted quarry.

Previously, the grade of waste material was considered as below 58%

Fe, but at present the grade of waste material is fixed as below 45%. So,

the old waste of Nadidih mines at present are considered as low grade

non-saleable ore.

(1) The waste dumping sites are proposed to be surrounded by

retaining wall and garland drain.

(2) The waste dumps are proposed to be formed by making terraces of

height of 8m to 12m, width 8 m to 12 m and ultimate slope of 370

to 400.

(3) Any rain cuts developed in old dump slopes are proposed to be

leveled and maintained properly by planting saplings and grass.

(4) Garland drains at the toe of the dump are proposed to be

connected with a series of settling tanks which will allow the

settling of silt in it. The silt free water will ultimately go out of the

lease hold. The garland drain will have check weirs/waffle wall at

regular interval to check flow of silt/debris



(5) The dead slope of the dump is to be covered by plantation. The

dump slopes where plantations are already completed are

proposed to be maintained properly.

(6) Coir matting is also proposed on the dead dump slope.
