    Mineral Commodity Profiles: Antimony

    Domestic production of antimony as a principal mine product (that is, from antimony ores) was as high as 5,000 t in 1943; in 1948, it peaked at about 5,900 t. Most of the production in those years came from the Yellow Pine Mine, in Idaho. After the early 1950s, production as a principal product dropped well below 1,000 metric tons per year (t/yr).

    Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite (antimony sulfide) and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing minerals include sibiconite, tetrahedrite and ullmannite. It is mined in China, Bolivia, South Africa and Mexico.

    Antimony Wikipedia. The extraction of antimony from ores depends on the quality and composition of the ore. Most antimony is mined as the sulfide; lower-grade ores are concentrated by froth flotation,while higher-grade ores are heated to 500–600 °C, the temperature at which stibnite melts and separates from the gangue minerals.

    The End of High-Grade Antimony Reserves in China the

    The best picture I can draw from Source B and Source A\'s comments as far as overall domestic mine supply of antimony in China in the coming years is the logical one anyway: that with higher grade ore running out, grades (whatever they may be) from Chinese antimony sources will continue to decline.

    Antimony Mining Encyclopedia of Arkansas

    Antimony (Sb) is a hard, brittle, silver-white metal with a relatively high specific gravity (6.69) and a relatively low melting temperature. Antimony is a constituent in some alloys. The presence of this metal hardens the alloy, lowers the melting point, and decreases contraction during solidification. The metal’s main use is to impart stiffness and hardness to lead alloys. Antimony
