Cu3FeS5

Cu3FeS5 is a mineral that belongs to the sulfosalt group. It is a relatively rare compound and is known by its mineral name, huberite. The crystal structure of Cu3FeS5 is complex, and it crystallizes in the monoclinic system. Its chemical formula indicates that it is composed of copper, iron, and sulfur in a specific stoichiometric ratio.

This mineral is typically found in hydrothermal deposits, often associated with other sulfide minerals such as chalcopyrite and pyrite. The formation conditions for Cu3FeS5 are thought to involve moderate to low temperatures and specific sulfur fugacities. Its occurrence is limited to certain geological environments, which contributes to its rarity.

Huberite, or Cu3FeS5, is not a commercially significant mineral for extraction of its constituent elements. Its primary interest lies in its mineralogical and crystallographic properties. Research into its crystal structure and chemical bonding provides insights into the behavior of sulfosalt minerals and their formation processes in geological settings. The physical properties, such as its hardness and specific gravity, are characteristic of minerals within the sulfosalt classification.
