Stibnite. Stibnite (antimony sulphide) is the main ore mineral of the metal antimony. Small amounts of antimony minerals were found in many Cornish mines but only a few were worked for antimony. Fewer still tried to produce it as their single main product. Most of these mines were in the north of the county.
