Hunan Gold Antimony Output Falls as Ore Supply Tightens in China

Hunan Gold

Hunan Gold antimony output fell sharply in 2025 as China’s domestic ore availability weakened and overseas feedstock flows shifted toward non-Chinese smelters. The major Chinese antimony producer reported 22,998t of antimony products during the year, down 21% from 29,209t in 2024.

The decline continues a multi-year downward trend. Hunan Gold antimony output was also below 31,005t in 2023, 30,715t in 2022 and 39,310t in 2021, showing how resource depletion and feedstock competition are weighing on Chinese production.

Hunan Gold antimony output matters because China remains central to global antimony supply, while antimony is increasingly important for flame retardants, military applications, lead alloys, batteries, cables and strategic industrial uses. Lower output from a major Chinese producer reinforces concerns over tightening availability.

Resource Depletion and Import Competition Reduce Feedstock Access

China’s domestic antimony resources have continued to decline after years of over-exploitation. This has limited ore availability for smelters and placed more pressure on producers that depend on both domestic mines and imported feedstock.

Import supply has also become more difficult. Key overseas ore suppliers have diverted more material to smelters outside China, where buyers are willing to pay higher prices to secure supply.

This shift reflects firmer global antimony prices after China imposed stricter dual-use item export controls. The policy tightened ex-China availability and encouraged foreign buyers to compete more aggressively for ore and intermediate supply.

The result is a structural squeeze for Chinese antimony producers. They face declining domestic resources, stronger competition for imported ore and a more fragmented international feedstock market.

Product Mix Shows Pressure Across Antimony Chain

Hunan Gold’s 2025 antimony production included 5,823t of antimony metal, 9,524t of antimony trioxide, 4,842t of sodium antimonate, 2,506t of ethylene glycol antimony and 303t of antimony oxide masterbatch.

Antimony trioxide remained the company’s largest antimony product by volume. It is widely used in flame retardant systems, making it important for plastics, electronics, textiles and industrial safety applications.

Antimony metal remains strategically important for alloying and defense-linked uses. Sodium antimonate and ethylene glycol antimony also support downstream chemical and industrial applications, linking ore supply constraints to multiple end markets.

Hunan Gold also produced 61t of gold in 2025, up 32% from a year earlier, while tungsten concentrate output fell by 10% to 908t. This shows that the company’s broader metals portfolio performed unevenly, with antimony facing the clearest supply-side pressure.

The Metalnomist Commentary

Hunan Gold’s lower output shows that China’s antimony position is being squeezed from both sides: depleted domestic resources and stronger overseas competition for ore. For global buyers, the key risk is that export controls and falling Chinese output reinforce each other, keeping antimony supply tight.
