Hindustan Copper Limited
is the sole integrated producer of
primary copper in India. The company was incorporated in Public Sector on
9th November 1967 to take over the plants and mines at Khetri,
Kolihan in Rajasthan and Rakha Copper Project in Jharkhand from National
Mineral Development Corporation Limited.
In 1972 M/S
Indian Copper Corporation Limited, Private Sector Company, located at
Ghatsila, Jharkhand with Smelter and Refinery was Nationalized and made
part of HCL. Hindustan Copper Limited developed Malanjkhand Copper Project
in Madhya Pradesh, the largest hard rock open pit mine in the country
which was dedicated to the nation on 12th November 1982.
Further in 1990 a Continuous Cast Wire Rod plant of South Wire Technology
was commissioned at Taloja in Maharashtra.
The introduction of reform process in 1991 was a land mark of India’s economic growth. In 1992, Government of India dismantled the system of canalising as well as the system of administered pricing. Subsequently customs duty on import of concentrate and refined copper were also reduced considerably. As a result of this the domestic price of copper is now linked with the international price. This change has thrown fresh challenges to HCL. HCL is striving its best to cope with these challenges and has carried out its capital restructuring in September 1998. HCL has also prepared a Turn Around strategy consisting of down sizing manpower, capacity enhancement, cost reduction etc. It has shutdown its high cost mines in the Singhbhum belt and separated the employees through a very just and fair Voluntary Retirement Scheme. Government of India has planned to disinvest HCL’s mines and flash smelter and refinery (31,000 TPA capacity) at Khetri Copper Complex and South Wire CC Rod Plant (60,000 TPA) at Taloja.
HCL shares are
listed at Mumbai, Delhi, Calcutta, Madras, Ahmedabad exchanges.
HCL was the first Indian Copper producer to get ISO-9002 certificate for its Continuous Cast Wire Rod Plant. ISO-9002 certificate has also been awarded for its Cathode produced at its refineries at Indian Copper Complex and Khetri Copper Complex
HINDCOP RODS are
manufactured with the highest quality of copper to meet the
most exacting requirements of the wire drawing industry in
electrical, mechanical and chemical properties.
Hindustan Copper Ltd., since its inception, has made significant contribution for the upliftment of living conditions of the people of the areas where it had established its production units and mines. These areas were in Rajasthan, Bihar, Madhya Pradesh and Maharashtra and were comparatively rural and backward. HCL, has undertaken the following social activities under its rural development programme :
Clean drinking water :
Adult Education Classes :
Rural Medical Camps :
Vocational Centres :
HCL’s units located in different areas
had training centres, who in turn organised training camps for women
belonging to economically weaker sections of the society. Training in
basket weaving, caning of chairs, stitching of hand gloves used in the
plants are some of the occupations which became popular in rural areas.
Abatement of Pollution :
Hindustan Copper Limited is fully committed to the
concept of operating in an Environment friendly atmosphere.
Limited has to its credit some major
contributions towards technological improvements in mining, beneficiation,
smelting, hydrometallurgy and by-product recovery. Some of the areas where
Hindustan Copper Limited has introduced new technology are
Trackless mining has helped in rapid development of mines
enabling higher levels of production and productivity comparable to
Raising is one of the most difficult of mining operation,
HCL has developed and perfected the concept of drop raising over 60m
intervals. This has resulted in increased-safety and higher progress. A
pattern of five 6” diameter holes has been standardized for the crater
method of blasting the raises sequentially.
DIAMETER BLAST HOLE STOPING
HCL has developed single sub-level method of stoping using
large diameter (162 mm) blast holes over level intervals of 50 to 60
meters. Need to have intermediate sub-level for drilling has been
eliminated in this method. Excellent fragmentation has been achieved. Benefits of new stoping method compared with the conventional sub-level
stoping methods are:
For mining flat dipping ore bodies, timber support was
common in early days. With the need to mine over a large width. HCL
developed very simple but effective methods of rock bolting using cement
grouted steel rods. This has resulted in the improvement of ground
conditions ensuring higher safety standards.
POST PILLAR STOPING
HCL has developed the post-pillar method of
mining for adoption in flatly dipping wide ore bodies in ICC group of
mines. This mining method has enabled the production rates to go up as
compared to room and pillar stopes. Electrically operated LHD 's have been
introduced at ICC for operating in these stopes. The output per man shift
has increased and the stoping cost has come down substantially. Hydraulic
filling of stopes with classified mill tailings has been established as a
standard practice at the ICC resulting in regional improvement in ground
HCL has also taken the lead in introducing
oxygen enrichment in the converters at KCC and ICC resulting in effective
control of accumulation of secondary products in smelting. HCL has also
introduced oxygen enrichment in process air in flash furnace to
effectively increase the capacity of the existing smelters for meeting
increased production commitments.
Occurrences of large quantities of oxidized
ore and lean grade sulphide ore at Malajkhand has impelled the company to
extract copper values in the ore by dump leaching otherwise uneconomical
by conventional methods. The dump is sprayed with dilute acidified
solutions to dissolve copper minerals. The end products of this leaching
operation is a pregnant liquor of copper sulphate. The leached liquor is
then treated to recover copper metal.
HCL has established well equipped R&D facility at KCC and ICC. The R&D section is fully responsible for improvement in quality of the products, control of quality of raw materials, improvement of recoveries and for maximizing the recovery of by-products, HCL has developed its own Precious Metal Recovery plant which is now operating at ICC successfully. A Tellurium Recovery Plant has also been developed by R&D Wing. Extensively trails are going on for recovering cobalt, nickel and copper powder from converter slag. Attempts are also being made for reducing the losses from slag.

TEN YEARS AT GLANCE
A skilled, committed, motivated and dedicated workforce led by a team of experienced and specialized managers is the strength of HCL. The Company believes in conducting regular and structured training programmes for development and skill up-gradation of its employees and also to prepare them to face future challenges. A highly successful suggestion scheme encourages suggestions from employees and rewards useful suggestions. HCL is committed to participative management through Shop Councils and Joint Councils at its projects and Joint Consultative Committee and National Joint Committee for Copper at the apex level to enable participation of its workers in management. The Company has excellent industrial relations.
Strength of Executives and Staff as of 1st August 2005
High quality of product and associated
customer satisfaction is of supreme importance in HCL’s operations. All
actions are directed to produce a quality which not only satisfies the
customers but prove to be a “CUSTOMERS’ DELIGHT”. In order to
achieve this the Company has
accredited itself with ISO 9002 certification for all its products viz.: Copper Cathode and Copper CC
Wirerods. Cathodes produced at Khetri Copper Complex, Rajasthan and Indian
Copper Complex, Bihar are ISO 9002 accredited . HCL is the FIRST ISO
accredited Company in India in copper production field.
All the units of HCL have
adequate modern controls, test and analysis facilities to ensure proper quality at all
stages of operation. The raw material input checks , in process controls
and final testing of the product are all carried out as per laid down
procedures . The final product of copper cathode are sampled batch wise
and analysed by sophisticated instruments like direct reading Emission Spectrometer, Atomic
Absorption Spectro Photometers and LECO Oxygen Analyser.
At Taloja (C C Rod plant) cathodes are received along with
their analysis certificates and finally Wirerods are produced by the
Southwire Technology. To ensure quality of the product following
in-process checks and controls are routinely exercised as per a laid down
Final CC rods are subjected to the following qualifying tests before the rods are marketed.
