No.4, Chitradurga-577501, State-Karnataka, is a Government of Karnataka Undertaking
(Established in 1947 as Hyderabad Gold Mines) mine, has the unique distinction of being the only
producer of primary gold in the country.
HGML has been active in the exploration, development and exploitation of gold deposits occurring
in Karnataka. The Company's Corporate Office is situated in Bangalore and it operates two units-
The Hutti Gold unit (HGU), in Raichur district and the Chitradurga Gold Unit (CGU) in Chitradurga
district with an operating mine at Ajjanahalli (Tumkur District). HGU is a fully integrated unit with a
capacity to produce 5, 50,000 tons per annum.
The HGML currently processes ore from Hutti Gold Mine and two satellite mines at Uti (opencast)
and Hira-Buddinni (Exploratory underground mine). Major expansion including the extended
capacity of the metallurgical plan in phased manner is also under consideration. However, CGU's
operations for gold mining and processing ore temporarily suspended and the company has
diversified into wind form project and as established 9.3 MW in its leased premises.
Ingaldal Copper Mines
Workings for Copper were first noticed by R.B Foote in 1886 on the Belligudda Hill of Ingaldal area.
The department of mines and geology carried out prospecting of the mineral bearing areas in the
state in 1927, and selected Ingaldal for its first operation.
The exploratory work consisted of cleaning up the old adit for a length of 6 mtrs. A winze was also
sunk to a depth of 10 mtrs below the old workings. The results indicated that mineralization was

fairly strong on the northern section averaging 8% copper while on the south pyrite was more
pronounced. The prospecting work carried out was of a few feet laterally and at depth, no attempt
was made at detailed exploration to estimate the possible reserves and grade.
HGML obtained Mining Lease (ML No: 2490, Period: 6-3-1993 to 5-3-2013). Mining activities were
held at Ingaldal Copper Mine from 1965 to 1994. Mining work has been suspended in 1994. Now
HGML is planning to restart the Copper mining at Ingaldal by utilizing their experience of operating
(mining & beneficiation) a copper mines. Accordingly, Mining Plan has been prepared in 1989 for
submission to Indian Bureau of Mines (IBM) for accordance of its approval. The ultimate rate of
production (maximum rated capacity) of copper ore in ingadal copper mine is 250 TPD.
M/s Ingaldal Copper Limited has been granted the mining lease (No. 2490) vide letter no.
KNT/CTD/CU-1-SZ dated: 29.03.1989 from Indian Bureau of Mines over an extent of 259 ha in
Ingaldal in Chitradurga District of Karnataka state. The lease period granted will be expired in the
year 2013.
(ii) Brief Description of Nature of the Project.
Ingaldal copper mine is situated near Bangalore-Bombay National Highway at about 10 Kms from
Chitradurga town (Karnataka State).
This mine was earlier worked during 1965 to 1994 period. Between 1964’s and 70’s State
Department of Mines and geology & GSI had carried out detailed exploration of this deposit.
The Ingaldal Mine is an underground mine which will be worked using the existing openings. The
copper bearing ore will be treated in beneficiation plant with froth floatation technique for
recovering copper. The beneficiation plant is located near the mines site and is an integral part of
the mines. The method of mining will be - overhand stoping by cut and fill method. Since back
filling of the stopes will be continuously done, the location of the plant is within the mining lease
area. The maximum rated capacity of mining and beneficiation plant would be 250 tons per day.

(iii) Need for the Project and its importance to the country.
Hutti Gold Mines Ltd intends to mine & beneficiate 250 TPD of Copper. Hence, it is mandatory to
obtain Environmental Clearance from MoEF, New Delhi. Currently the mine is not working.. It is
planned to carry out detailed exploration by exploratory mining.
(iv) Demand Supply Gap
India's Copper demand will likely grow at least 8% to 10% as corporate build power units to meet
their electricity demands. The slower growth rate is attributed to the sharp decline in the demand
for jelly filled telecom cables, the largest user industry of copper in India. However, the demand
from power cables, winding, industrial applications and construction industry has increased.
Moreover, deficit in the other Asian countries helped the domestic producers to increase exports.
The size of Indian Copper Industry is around 4 lakh tons, which as percentage of world copper
market is 3 %.
The major copper producing companies in India are as follows

Stage-2
The bottom level is back stripped to a height of 3m from level back or 5m from the floor of the level
and the back is advanced. The clearance between the stuff and back of the stripped area shall not
exceed 1.5 m.
Stage-3
After completing the back stripping, the level is cleared of the stuff and reinforced back concreting
is taken up. The back concreting is done at a height of 2.20m. Above the rail level. The reinforced
concreting is done to a thickness of 60 cm to the entire length and width of the stope, leaving chute
gaps at convenient intervals.
Stage-4
When the level back concreting is completed to the stope length, the stoping operation is
commenced from winze/rise point. The bench height for stoping shall be about 3 m. Breast holes
are drilled and benches are advanced on either side of winzes/rises. Crib setted ladderways are
provided at square ends. 1/3rd of the broken rock is removed and the remaining 2/3rd of the broken
rock is allowed to pile up above the concrete mats. During this operation systematic timbering rules
as applied to shrinkage stopes shall be followed.
Stage-5
The back of the stope is advanced upto the top of the level, pilling the stuff in the stope, when the
back of the stope approaches the level, level pillars are left in the upper level, with gaps. This way
the extraction of the block is completed.

burden to a depth of 90 cm to 1.0 m. The method of drilling is pyramid cut. Special gelatin of 80% is
used with delay detonators for blasting. The consumption of explosives is about 20 kgs/m of leniar
advance.
Stoping (shrinkage method)
The method of stoping practiced is over hand flat back shrinkage method by breasting along the
strike in slices of 3m. Parallel hole (Drag Cut) are drilled to a depth of 1.2m within spacing and
burden of 60 cm. Special gelatin / kelvex are used with delay detonators for blasting. The powder
factor is 0.60 m3 / kg of explosive in stope.
A magazine of 3 MT capacity is built on the surface to store the explosives and detonators. The
average consumption of explosives / day is about 200 kg.
e) Mineral Beneficiation
ROM Grade of the mine is 0.8% to 1.2%
The chalcopyrite ore is subjected to crushing in jaw and gyratory crushers and the crushed material
is fed to ball mill where size reduction takes place by wet grinding. The beneficiation is done by
froth flotation technique. The fine ore is conditioned with PH Regulator, a collector, and frother, and
floated once and cleaned twice to obtain enriched copper concentrates.
(vi) Raw Material/ Consumables Required along with estimated quantity, likely source,
marketing area of final product, mode of transport of raw material and finished product.
Since this is a mining project, there are no raw materials as such, though various consumable will
be required in mining and processing operations.
Pre Feasibility Report of Copper Mining Project of Ingaldal Copper Mines Ltd.
Page 12
(vii) Resource optimization/ recycling and reuse envisaged in project, if any, should be
briefly outlined.
Land: Since there is limitation of extent of land availability in the area, the process has been
designed very efficiently as regards space utilization. It is expected that the entire plant will be put
in a limited space.
Water: An effort has been made to reuse the mines water for mineral processing operations and
the plant has been designed in such a manner that most of the process water is recycled and reused
in the plant.
Plant Tailings: The mill tailings will be used for back filling of stopes/ mined out area and this
would lead to lesser amount of mill tailings to be stored above ground.
(viii) Availability of water, its source, Energy/power requirement and source should be
given.
Water Requirement & Source:
1lakhs gallon/250 TPD Process (378.5 KLD)
Source: Bore wells and underground seepage water
Energy / Power Requirement & Source:
1200 KVA (Domestic purpose-100KVA, Mining & Milling-1100KVA)
Source: Karnataka Electricity Board
2 No’s DG Sets of 1000 KVA & 500 KVA for stand by purpose
(ix) Quantity of wastes to be generated (liquid and solid) and scheme for their
management / disposal.
Black rock/waste rock obtained from the mine is used for stope filling. Mill tailing to an order of
150 MT to 200 MT are disposed to the tailing bund. The rejects are being used for stope filling after
classification. The final tailings obtained from scavenger cells of the mill are fed to 12” cyclone
having 2” spigot for classification. The classified sizes of underflow and overflow are as follows.
Cyclone underflow Cyclone overflow
+200 : 74% +200 :1.5%
-200 +350 :805% -200 +350 :2.0%
-350 :17.5% -350 :96.5%
Pre Feasibility Report of Copper Mining Project of Ingaldal Copper Mines Ltd.
Page 13
After classification the underflow is pumped to the sand storage bin by using a slurry sump. The
overflow is left into the tailing bund which flows by gravity. The capacity of the storage bunker is
120 MT. From the storage bunker the sand by gravity is conveyed down via pipes of 4” and 3” for
stope filling. The area of the tailing bund is specially acquired to build up the mill tailings to prevent
pollution. Drainages have been out right round the bund to prevent accumulated rain water and
washing of the bund by rain water. Afforestation has been done on the part of the dumps to prevent
erosion of sand and to control dust. Mostly Eucalyptus have been planted on the tailing dumps with
a spacing of 1.5 m to 2.5m. The survival rate is 80%. Care is taken in the initial nursery stages by
mixing red earth and manure along with the mill waste in the pits. Further the pits are periodically
watered to ensure the growth. At present the maximum height of the dump varies between 12m to
15m.

(iii) Green Belt
The mine falls under hilly and flat terrain with cultivable agricultural land. Since it is an
underground mining and only 20.23 hectares of land is required for surface rights, the surface
environment is not disturbed by the mining activity since the mining operations are below ground.
The ore beneficiation do not imbalance the environment, since adequate care is taken for the
disposal of waste, by constructing tailing bunds/dumps, and contamination is prevented by cutting
out storm water drains to prevent the carry of waste material. Massive afforestation work is being
carried out on the slopes of the hill both by the mines and the government forest department.
The dumps are stabilized by pitching on the sides, and by planting trees on the top of the dumps.
Agave and bellary Jolli are planted at the sides of the dumps to minimize the erosion and in addition
to this the mill tailing are let into different step dumps to allow the tailing waste to consolidate.
When once the dumps attain the maximum height the letting of the disposal of waste the dump is
topped. Seedlings and plantation are carried on top of the dumps.
(iv) Social Infrastructure
It is expected that the project will lead to much needed employment opportunities in the villages
which will contribute to the socio-economic development of this area. The site services at mines
