Bornite (Cu 5 FeS 4) is a kind of copper resource that is relatively widespread on EarthBio-hydrometallurgy (bioleaching) is considered an economically promising technology for clean extraction of sulfide minerals such as chalcopyrite (CuFeS 2), pyrite (FeS 2) and chalcocite (Cu 2 S) []Hence, bioleaching of bornite is an important research topic and the dissolution mechanisms of bornite ....

Chalcocite

A pseudomorph is a mineral that has replaced another mineral atom by atom, but it leaves the original mineral's crystal shape intact Chalcocite has been known to form pseudomorphs of the minerals bornite, covellite, chalcopyrite, pyrite, enargite, millerite, galena and sphalerite See also Copper(I) sulfide; Copper monosulfide...
