Sulfosalt minerals

Sulfosalt minerals are those complex sulfide minerals with the general formula: AmBnSp; where A represents a metal such as copper, lead, silver, iron and rarely mercury, zinc, vanadium; B usually represents semi-metal such as arsenic, antimony, bismuth and rarely germanium, or metals like tin and rarely vanadium; and S is sulfur or rarely selenium or/and tellurium.[1] The Strunz classification includes the sulfosalts in a sulfides and sulfosalts superclass.[1] A group which have a similar appearing formulas are the sulfarsenides (for example cobaltite (Co,Fe)AsS). In sulfarsenides the arsenic substitutes for sulfur whereas in the sulfosalts the arsenic substitutes for a metal cation.[2]

There are about 200 known sulfosalt minerals. Examples include:[3]
