Sulfosalt minerals are sulfide minerals with the general formula AmBnXp, where

The Strunz classification includes the sulfosalts in a sulfides and sulfosalts superclass. [1] A group which have similar appearing formulas are the sulfarsenides (for example cobaltite (Co,Fe)AsS). In sulfarsenides the arsenic substitutes for sulfide anions whereas in the sulfosalts the arsenic substitutes for a metal cation. [2]

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

Nickel–Strunz Classification -02- Sulfosalts

IMA-CNMNC proposes a new hierarchical scheme (Mills et al., 2009). This list uses the Classification of Nickel–Strunz (mindat.org, 10 ed, pending publication).

Class: sulfosalts

Synthetic sulfosalts

Many sulfosalts can be prepared in the laboratory, including many that do not occur in nature. [4] [ which? ]
