Location 14 km from Udaipur, Rajasthan, India
Background Hindustan Zinc Limited was incorporated from the erstwhile Metal Corporation of India on 10th January 1966 as a Public Sector Undertaking. In April 2002, Sterlite Industries (India) Limited made an open offer for acquisition of shares of the company consequent to the disinvestment of Government of India’s stake (26%) including management control to Sterlite and pursuant to the regulations of SEBI Regulations 1997 acquired additional 20% of shares from public. In August 2003, Sterlite Industries acquired additional shares to the extent of 18.92% of the paid up capital from Government of India (GOI).
The Zinc business of Vedanta is managed within Hindustan Zinc Limited.  HZL is India’s only integrated zinc company, operating from mine to finished metal and supplied around 73% of India’s zinc requirements in 2005-06. At the base of the company is the Rampura Agucha mine with its low cost and consistently high grade ore.

News October 22, 2009 - Vedanta Resources Group firm Hindustan Zinc today reported 2.55 per cent decline in its net profit at Rs 934.95 crore for the second quarter of the current fiscal over the year-ago period mainly on lower realisations from by-products like sulphuric acid sales.  "The positive impact of higher volume, operational efficiencies, lower input cost and rupee depreciation on net profit was more than offset by the sharp decline in the by- product credit realisations" the company said in a statement.  In July-September quarter last year, the company had a net profit of Rs 960 crore.  Hindustan Zinc, which primarily mines Zinc and Lead and Silver, also produces sulphuric acid and cadamium as by- products in bulk.  Rates of sulphuric acid have plummeted to USD 200 a tonne level after hitting a peak of around USD 1,200 per tonne last year, a Hindustan Zinc spokesperson said.
