Hindustan Zinc Limited (HZL) was incorporated in January, 1966 as a public sector company, after the takeover of the erstwhile Metal Corporation of India Limited, to develop mining and smelting capacities and to substantially meet the domestic demand of zinc and lead metals.
Hindustan Zinc Limited is a Vedanta Group Company in Zinc, Silver and Lead business which is one of the world's largest integrated producers of zinc and are among leading global lead and silver producers. It is one of the lowest cost producers in the world and are well placed to serve the growing demand of Asian countries.Hindustan Zinc is a subsidiary of the BSE and NSE listed Vedanta Limited (ADRs listed on the NYSE which was earlier known as Sesa Sterlite Limited), a part of London listed diversified metals and mining major, Vedanta Resources plc.
The core business comprises of mining and smelting of zinc and lead along with captive power generation. They have a metal production capacity of over one million tonnes per annum with the key lead-zinc mines in Rampura Agucha and Sindesar Khurd; and key modern smelting complexes in Chanderiya and Dariba, all in the state of Rajasthan in India. With 404.4 million tonnes of reserves and resources, their exploration programme is integral to our growth and future expansions.They own 474 MW of coal based thermal captive power plants in Rajasthan to support the metallurgical operations and in addition, their environment friendly power generation includes 274 MW of wind energy, 16 MW of solar power and 35.4 MW from waste heat generation.
Chanderiya Lead-Zinc Smelter is the one of the largest zinc-lead smelting complexes in the world. Its current metal production capacity is 610,000 tonnes per annum which is 525,000 tonnes per annum of zinc and 85,000 tonnes per annum of lead. In the end of March 2017, Chanderiya produced 435,666 MT of zinc and 51,759 MT of lead. The main products are special high grade (SHG) zinc, continuous galvanizing grade (CGG) zinc, prime western (PW) zinc and pure lead and it also produces a number of valuable by-products including silver.
Chanderiya is located 110 Kms North of Udaipur in the State of Rajasthan, India. With an initial production capacity of 70,000 MT per annum of zinc and 35,000 MT per annum of lead, it was commissioned in the year 1991. In the past 6 years, the capacity of the plant has been expanded five folds to its current capacity of 525,000 MT per annum of zinc and 85,000 MT per annum of lead.
Chanderiya Lead-Zinc Smelting complex comprises of one lead-zinc Pyrometallurgical smelter (35,000 MT lead and 105,000 MT zinc), one Ausmelt lead smelter (50,000 MT) and two Hydro metallurgical zinc smelters (Hydro I & Hydro II of 210,000 MT each). It employs Roast Leach Electro-winning Technology in its Hydro metallurgical smelters, Imperial Smelting Process in lead-zinc smelter, and Top Submerged Lance Technology (Designed by M/S Ausmelt Ltd., Australia) coupled with Cansolv Technology for its lead smelter. The complex also has 234 MW (77 + 77 + 80 MW) of captive thermal power capacity to supply the power requirements for its metallurgical operations and it also has 14.81 MW of DG set and 13.7 MW (9.4 MW+4.3 MW) of power generation capacity through waste heat recovery.
