Sulfosalt minerals

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.
