The world's fourth most widely used metal, mostly for galvanizing steel against corrosion.
Zinc is the fourth most widely used metal globally after iron, aluminium and copper, used predominantly (~60% of primary output) to galvanize steel against corrosion, plus die-casting alloys, brass, and zinc oxide and chemicals. Global mine production runs approximately 13 million tonnes per year of contained zinc, with refined (smelted) output around 13.7-13.9 million tonnes per year. Unlike lead, zinc's supply chain remains overwhelmingly a mining story rather than a recycling one.

China alone accounts for roughly a third of world zinc mine output. India is a top-4 global producer, driven almost entirely by Hindustan Zinc's Rajasthan operations (~75-80% of India's domestic zinc-lead market). Source: USGS Mineral Commodity Summaries 2026.
USGS puts world zinc reserves at about 240 million tonnes, with total identified resources around 1.9 billion tonnes. Australia (about 64 Mt) and China (about 60 Mt) together hold roughly half; Russia (29 Mt), Peru (18 Mt), Mexico (14 Mt) and India (10 Mt) follow. Australia's reserves sit well ahead of its #3 production rank, which points to long-term supply growth potential. India's 10 Mt of reserves against about 0.87 Mt of annual output is roughly 11 to 12 years at today's rate, a figure worth weighing in any multi-year domestic sourcing plan, bearing in mind that reserves are revised upward as exploration and prices allow.
Mining and refining are not evenly distributed the same way. China alone represents approximately 48% of world zinc refining capacity, meaningfully higher than its ~32% share of mine production, meaning concentrate mined elsewhere often still flows toward Chinese smelters. Other Asian refiners (South Korea, India, Japan, Kazakhstan) account for a further ~16% of capacity, and the EU another ~16%. This concentration is a structural chokepoint worth factoring into any long-term sourcing or price-risk strategy.
Zinc recycling is real but structurally limited compared to lead. Only around 13-15% of refined zinc comes from secondary (recycled) material: scrap, EAF (electric arc furnace) dust, and galvanizing residues. The core constraint is not recycling technology but availability: roughly 60% of primary zinc goes into galvanized steel that can stay in service for decades (buildings, vehicles, infrastructure), so it simply has not reached end-of-life yet. Of the zinc scrap that genuinely is available for recycling, capture rates are strong (over 80% globally recycled), and Western Europe's rolled-zinc recycling exceeds 95% (France ~98%). The overall end-of-life recycling rate across all zinc uses is estimated around 33-34%.
India's zinc is effectively a one-company story. Hindustan Zinc's Rajasthan mines (Rampura Agucha, Sindesar Khurd, Zawar, Rajpura Dariba and Kayad) supply the bulk of domestic zinc and lead concentrate, and most of that concentrate feeds Hindustan Zinc's own smelters. Independent domestic concentrate supply is therefore thin, which is why traders, downstream zinc-product makers and imports carry more weight for buyers outside Hindustan Zinc's own chain than they would in a more fragmented market.
Zinc trades on the LME as Special High Grade (99.995%), and the physical price is LME plus a regional premium. Concentrate (typically 50-55% zinc) is sold to smelters under annual benchmark contracts, with the smelter keeping a treatment charge (TC) and typically paying for only about 85% of the contained zinc. Penalties apply for iron, arsenic, mercury and other impurities, and concentrate is shipped in bulk cargoes, so volume and port logistics matter as much as grade.
Because most zinc is consumed by galvanizers and die-casters who buy ingot, the market is more concentrate-driven than lead: when mine supply is tight, treatment charges fall and smelters compete for ore. Traded forms include SHG ingot, jumbo blocks, die-casting alloy ingots (Zamak), zinc dross and ash, and concentrate.
Zinc supplier research should weight primary miners and concentrate traders far more heavily than scrap/recycling operators, the reverse of lead sourcing.
