Antimony ore in the Fairbanks district, Alaska

The ores were exposed largely as a result of lode gold mining, but at two periods in the past, high prices for antimony ore warranted an independent production and about 2500 tons of stibnite ore was shipped. The sulfide deposits occupy the same fractures along which a gold-quartz mineralization of greater economic importance occurred; and both ...

Slate Creek (ARDF #MM153) Sb

The Slate Creek or Taylor antimony mine has produced a total of about 679 tons of hand-picked antimony ore. Production from the time the mine opened before 1916 to the end of World War II totaled about 325 tons of ore averaging 49 percent antimony. From World War II to 1983, the mine produced about 354 tons of ore that averaged 60 percent antimony.

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 ...
