India is one of the world’s most important zinc producers, with the country accounting for approximately 4 to 5 percent of global zinc mine production and approximately 6 percent of global refined zinc output. India’s zinc market is uniquely concentrated around Hindustan Zinc Limited, the world’s second-largest integrated zinc-lead producer which commands approximately 75 to 80 percent of India’s primary zinc market and generates export revenues across 40 plus countries. India’s zinc consumption is growing at approximately 6 to 8 percent annually driven by the steel sector’s growing use of galvanised steel for automotive, construction, and infrastructure applications, the battery sector’s increasing use of zinc in zinc-manganese oxide and zinc-air batteries, and the die-casting industry serving automotive components. Zinc prices have been volatile globally with LME zinc trading between USD 2,400 and USD 3,200 per tonne in 2025 to 2026, directly impacting the profitability of primary zinc producers. The Union Budget 2026-27’s commitment to infrastructure and housing construction is supporting strong domestic zinc demand growth. Let us have a look at the top 10 zinc manufacturing companies in India for the year 2026.
1. Hindustan Zinc Limited
Hindustan Zinc Limited, a subsidiary of Vedanta Limited incorporated in the year 1966 and the world’s second-largest integrated zinc producer and third-largest silver producer, commands approximately 75 to 80 percent of India’s primary zinc market through its fully integrated zinc-lead-silver mines and smelters in Rajasthan and Uttarakhand. The company’s Sindesar Khurd underground mine in Rajasthan is among the world’s largest underground zinc mines, and its Dariba Smelting Complex processes zinc and lead concentrates into refined metal of 99.99 percent purity. Hindustan Zinc generates substantial silver byproduct revenue — approximately 30 crore ounces of silver annually — adding a precious metals dimension to its base metals business. Revenue from zinc and silver production generates the majority of HZL’s approximately Rs 28,000 to 30,000 crore annual revenue.
Hindustan Zinc serves India’s galvanising, battery, die-casting, and chemical industries with its refined zinc and lead products, and its world-leading position in integrated zinc production combined with rising zinc demand from India’s infrastructure construction and battery sectors positions it as one of India’s most strategically important metals companies for the country’s industrial and energy transition economy.
2. Vedanta Limited (Parent of Hindustan Zinc)
Vedanta Limited, the Indian listed parent company of Hindustan Zinc and itself a global diversified natural resources company, holds a 64.92 percent controlling stake in Hindustan Zinc and consolidated the zinc business within its broader metals and mining portfolio spanning aluminium, copper, iron ore, oil and gas, and commercial power. Vedanta’s proposed demerger into six separately listed entities aims to unlock the underlying value of its individual business segments including its zinc holdings, which have historically traded at a discount to their standalone value when bundled within the diversified conglomerate structure.
Vedanta serves zinc investors through its controlling stake in Hindustan Zinc while simultaneously operating as India’s most diversified natural resources company, and its proposed demerger strategy to create focused standalone entities for each metals business reflects the market’s preference for pure-play metals exposure over conglomerate discount structures.
3. National Zinc (Government of India stake in HZL)
The Government of India holds approximately 29.54 percent of Hindustan Zinc Limited’s equity through its retained stake from the original privatisation of the company to Sterlite Industries now Vedanta in 2002, making it the second largest shareholder in India’s dominant zinc producer. The government’s stake represents one of India’s most valuable residual holdings from the privatisation era and generates significant dividend income annually. There have been periodic discussions about the government divesting its remaining HZL stake as part of its broader disinvestment program.
The Government of India’s stake in Hindustan Zinc makes it the second largest participant in India’s zinc mining and production sector, and its continued ownership alongside Vedanta reflects both the strategic importance of zinc as an industrial metal and the political sensitivity around further privatising a mineral resource company whose operations span ecologically sensitive mining regions in Rajasthan and Uttarakhand.
4. HZL (Dariba Smelting Complex)
The Dariba Smelting Complex, operated by Hindustan Zinc as one of its primary smelting facilities in Rajasthan, processes zinc and lead concentrates from HZL’s nearby mines into refined zinc ingots, zinc die-casting alloys, zinc oxide, and lead products for sale to domestic and international markets.
