The world's leading antimony-producing mine was a gold-antimony mine with 23,000-ton-per-year capacity in Russia. The mine had significantly reduced antimony production in 2021 through 2023 because
China is the biggest antimony ore producer but production has declined to 40,000 tons in 2023 from 61,000 tons in 2020 as a result of falling ore grades and more stringent environmental requirements.
"For example, the ancient Egyptians and early Hindus used stibnite, which is the major ore mineral for antimony, to produce black eye makeup as early as about 3100 B.C.," …
When used as an alloying element, antimony greatly increases the hardness and mechanical strength of lead. The main use of antimony is to harden lead in storage batteries, and it is increasingly being used in the semiconductor industry. Historically and economically, antimony is the second most important metallic commodity in Victoria, after gold.
The primary sources of antimony extraction are stibnite (antimony trisulfide) and valentinite (antimony xide). The extraction process typically involves several steps, including mining, concentration, and smelting. Mining involves the extraction of antimony-rich ore from underground or open pit mines.
ANTIMONY (Data in metric tons of contained antimony unless otherwise noted) Domestic Production and Use: In 2022, no marketable antimony was mined in the United States. A mine in Nevada . that had extracted about 800 tons of stibnite ore from 2013 through 2014 was placed on care-and-maintenance status in 2015 and had no reported production in 2022.
Most antimony occurs in scattered ore bodies that cannot be readily exploited by large-scale mining methods. ... rising antimony prices over the past five years have served to spur new mining activity and exploration around the world, especially in Australia and Mexico.
