Major Chinese non-ferrous metal producer Shenzhen Zhongjin Lingnan has restarted operations at its Fankou zinc-lead mine following a safety suspension. The resumption brings critical supply back online amid severe tightness in the domestic zinc concentrate market.
Safety Suspension and Production Capacity Impact
Mining operations were halted in August after a roof-collapse accident resulted in one fatality. The Fankou mine represents nearly half of Zhongjin Lingnan’s total concentrate output. The underground operation produces between 120,000 and 130,000 tonnes of contained zinc and lead per year.
The company has not disclosed total volume losses caused by the production pause. In 2025, Zhongjin Lingnan produced 253,805 tonnes of contained zinc and lead in concentrate across its mining portfolio.
Concentrate Shortage and Treatment Charge Pressures
The domestic zinc concentrate market in China remains extremely constrained. Global mine disruptions and elevated refined zinc production have exhausted spot inventories. Consequently, imported spot treatment charges fell to deeply negative levels between -$130 and -$105 per dry metric tonne.
Industry analysts expect the mine restart will do little to alter the tight spot market. Chinese smelters typically begin restocking concentrate inventories in early autumn ahead of winter operations. This seasonal demand will maintain severe downward pressure on treatment charges in the coming months.
Market Impact
○ Impacted Metals: Zinc concentrate, lead concentrate, refined zinc metal, refined lead metal
○ Direction: Stable
○ Time Horizon: Near-term
○ Affected Industries: Zinc Smelting, Galvanized Steel Manufacturing, Lead Refining, Chemical Processing

○ Watch Item: Track Chinese spot zinc treatment charges as smelters begin pre-winter concentrate inventory replenishment in October.
SuperMetalPrice Commentary:
While restarting the Fankou mine restores approximately 125,000 tonnes of annual contained zinc and lead capacity, it will not resolve the broader structural tightness in Chinese concentrate supply. Smelter margins remain under severe pressure from negative treatment charges.
With smelters entering seasonal pre-winter restocking, spot treatment charges are expected to stay deeply depressed. Smelters will depend heavily on high sulfuric acid byproduct credits to maintain operational profitability through the end of the year.
