Mining Antimony Ore

The most common antimony ore mineral is stibnite (Sb2 S3 ), but more than 100 other minerals also contain antimony. The presence of antimony in surface waters and groundwaters results primarily from rock weathering, soil runoff, and anthropogenic sources. Global emissions of antimony to the atmosphere average 6,100 metric tons per year.

And U.S. Antimony, an American company that operates the country's only antimony smelter, recently staked nearly 4,000 acres of claims around a World War I-era antimony mine in Alaska's Iinterior, some 20 miles southwest of Tok. The company's refinery, in Montana, is running at only 50% capacity, according to co-chief executive Gary Evans.

Historical records show that between 1915 and 1926, the project yielded 105 tonnes of ore with an average antimony grade of 57.2%. Some of this ore contained up to 59.5% antimony. The mineralization at the project is found within an east-west shear zone, with stibnite veins reaching widths of up to 1.2 metres and antimony grades of up to 59.5%.

Once mined, antimony ore needs to be processed into metal ingots, which are then used to produce antimony xide for flame retardants. This entire processing capacity is predominantly located in China. ... Although …

The techniques used in antimony mining vary based on the deposit. Open-pit mining is commonly used for extracting larger deposits, while underground mining might be employed for deeper ore bodies. The extraction process typically involves crushing and grinding followed by gravity separation or flotation to concentrate the ore.

The Company processes antimony ore primarily into antimony oxide, antimony metal, and antimony trisulfide. Our antimony oxide is used to form a flame-retardant system for plastics, rubber, fiberglass, textile goods, paints, coatings and paper, as a color fastener in paint, and as a phosphorescent agent in fluorescent light bulbs.

The MOU is non-binding and non-exclusive, initiating third-party engineering to evaluate a flowsheet suitable for different antimony ore types. The agreement comes at a crucial time as China, which dominates global antimony production, announced an enhanced ban on exports to the US on 3 December 2024.

USAC has produced various antimony products since 1969 and is a fully integrated mining, transportation, milling, smelting, and selling company. USAC operates the only significant antimony smelter in the United States and it is in a "sold out" condition.

In 2021, the global antimony ore and concentrate market was finally on the rise to reach $2.3B for the first time since 2018, thus ending a two-year declining trend.

Garner says that with the antimony price increasing to US$23,500 per tonne, plus the recently announced ban on Chinese exports, it is considered a good time to revisit the deposit. "The high-grade antimony mineralisation drilled in 2008 returned up to 17.3% antimony and is open down dip and along strike, representing a compelling drill target."
