Sulfosalt minerals are sulfide minerals with the general formula AmBnXp, whereA 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 X is sulfur or rarely selenium and/or tellurium.

The sulfide minerals are a class of minerals containing sulfide (S2−) or disulfide as the major anion. Some sulfide minerals are economically important as metal ores. The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulfarsenides and the sulfosalts. Sulfide minerals are inorganic compounds.
