Relation to Mining. Antimony rarely occurs in its native metallic form in nature. It easily combines with other elements, usually including sulfur, to form over 100 different minerals. Of these minerals, only stibnite (Sb2S3) is mined commercially as a source for metallic antimony. Antimony is found in trace amounts in silver, copper and lead ...
