Sulfosalt minerals

From Wikipedia, the free encyclopedia

Sulfosalt minerals are those complex sulfide minerals with the general formula: A_mB_nS_p; where A represents a metal such as copper, lead, or silver; B represents a semi-metal such as arsenic, antimony or bismuth; and S is sulfur or rarely selenium. In the more simple sulfosalt formulas m = p = 3n is an approximation.

There are about 200 known sulfosalt minerals, a few of the more common or important (as ore minerals) sulfosalt minerals are:

• Pyrargyrite Ag₃SbS₃
• Proustite Ag₃AsS₃
• Enargite Cu₃AsS₄
• Tetrahedrite Cu₁₂Sb₄S₁₃
• Tennantite Cu₁₂As₄S₁₃
• Bournonite PbCuSbS₃
• Jamesonite Pb₄FeSb₆S₁₄
