Sulfosalts

The minerals that make up the sulfosalt class are those in which a metal is combined with sulfur. There are nearly 100 sulfosalts, but many are rare.

The sulfosalts differ from the sulfides in that sulfides that contain a semi-metal such as antimony, arsenic or bismuth, they substitute in the sulfur positions, but in the sulfosalts they substitute for the metal ions and bond with the sulfurs.
