Antimony mining encyclopedia of arkansas,antimony is a hard, brittle, silver-white metal with a relatively high specific gravity 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 metals main use is to impart stiffness and hardness to lead alloys.

antimony also is used as an alloy, because it hardens other metals. alloyed with lead, it greatly improves the strength and hardness of lead. It also is used in semiconductors, diodes, infrared detectors, batteries and bullets. antimony compounds are used in paint pigments, enamels, glass and pottery.
It was in this mine that a new antimony mineral, sarabauite was discovered in 1977. It was named after the sarabau mining company between 1970 and 1982, the mine produced an estimated 5000 of 6068% Sb concentrates by the flotation method from about 50,000 crude ore.
