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. Feb 02, 2015· As regard the above subject,I came in contact with a geologist that offer to sell the antimony ore to me at a bearable amount and while reading different materials on this subject I think it worth researching into. the ore contain 48% antimony,14% zinc and few other metals.

ANTIMONY OXIDE LISTING BACKGROUND

The U.S. relies heavily on imports of antimony metal and ore in the production of antimony oxide. This is because domestic ore has high levels of arsenic, making use of this ore unattractive. In 1988, a total of 33,106 tons of ore was imported into the U.S., with China being the largest supplier.
