A review of major events, news, updates and trends in the global zinc mining and processing industry since September 2025 — market, supply and demand, projects, processing at current assets, company news including M&A, consumption and trade — with a timeline of major events and analysis of the economic, political and natural-disaster backdrop affecting operations.
This curated review covers 80 source-linked major events from 9 September 2025 to 18 September 2026, drawn from 47 distinct URLs across 25 independent hosts and checked through 12 October 2026. It is a selection of major events, not a claim that every worldwide zinc development was captured; each dot below is one event, sized by a 0–1 significance score.
Supply and processing. Mine supply improved at several large producers — Glencore's 2025 own-sourced zinc rose 7% and 2026 guidance sits at 700–740 kt, Kipushi ramped to a record 26,560 t of zinc in July 2026, and Boliden's Odda expansion entered hot commissioning — yet refined output stayed constrained by tight concentrate economics, power and acid costs, maintenance and unplanned plant outages. The result was a processing bottleneck and a regional mismatch rather than a simple global shortage. Teck guided Red Dog's 2026–2028 output lower on geotechnical slippage and falling grades, a note of caution on future concentrate supply.
Strategy and M&A. The 9 September 2025 Anglo American–Teck merger places Red Dog inside Anglo Teck; Korea Zinc's $7.4bn Tennessee refinery and mine restart — backed by $210m in US subsidies and $4.7bn of loans — would be the first US zinc refinery since the 1970s; and Boliden agreed to buy Votorantim's 64.68% controlling stake in Nexa for about $1.31bn in shares, with a minority tender offer planned after a Q1 2027 close. Western critical-minerals industrial policy is reshaping where zinc is refined.
Disruption and policy. The period's clearest weather event was intensive January 2026 rain in Portugal, which hit water management at Boliden's Somincor mine. Garpenberg's rock fall came from abnormal seismicity, and the Kazzinc Ust-Kamenogorsk blast and Nexa's Cajamarquilla and Três Marias incidents were industrial or geotechnical — operational events, not natural disasters. Policy overlays included China's anti-involution smelter capacity caps, EU/LME restrictions on Russian Chelyabinsk-brand zinc from July 2026, and Middle East conflict dislocating crude, refined products and sulphuric acid, raising diesel and acid costs for metallurgical plants.
Demand. Reported global refined demand grew, with China and India consumption stronger, but Chinese property-linked galvanizing demand stayed weak. Zinc demand remains anchored in galvanized steel, infrastructure, autos and renewables; increasingly it is trade flows and warehouse geography — not aggregate demand — that set regional premiums and tightness. Forward-looking items in the timeline (guidance, planned projects, expected closings) are forecasts, not completed outcomes.

Method: curated timeline of 80 source-linked major events in global zinc mining and processing, 9 Sep 2025 – 18 Sep 2026, one row per event with date, theme, organization, metric, cause, consequence and a 0–1 significance score; 47 distinct URLs across 25 independent hosts, no single URL backing more than 5 rows (6.3%). Research swept more than 700 authoritative-source results plus broader market, mine, processing and corporate searches; sources checked through 12 Oct 2026. A curated selection, not an exhaustive census; long event texts are shown in full in tooltips and the table, abbreviated in chart labels.
