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.〔(【引用サイトリンク】 Strunz classification of sulfides and sulfosalts )〕 The Strunz classification includes the sulfosalts in a ''sulfides and sulfosalts'' superclass.〔 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.〔Klein, Cornelis and Cornelius S. Hurlbut, 1985, ''Manual of Mineralogy'', 20th ed., John Wiley and Sons, New York ISBN 0-471-80580-7〕 There are about 200 known sulfosalt minerals. Examples include:〔Palache, C., H. Berman, and C.
