Some Galena may contain up to 1% silver in place of lead. The large volume of Galena that is processed for lead produces enough Silver as a by product to make Galena the leading ore of Silver. To quote Allen N Wollscheidt, "Galena, back 75 years ago, was the stuff -- the crystal -- of crystal radio sets.

Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb 2 S 3.This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. The name is from the Greek στίβι stibi through the Latin stibium as the old name for the mineral and the element antimony.

Stibnite Stibnite has the formula Sb2S3. It has a relative hardness of 2. It is the major ore of antimony. Deposited by alkaline waters, usually in association with quartz.
