Copper sulfide ore, which accounts for 80% of the copper resource, is the major source for the metallic copper [1]. The major copper sulfide ores contain chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), covellite (CuS), and chalcocite (Cu 2 S). The concentrates of copper from sulfides ores are generally performed by flotation and then processed by ...

Bornite, affectionately known as "peacock ore," is a stunning mineral admired for its iridescent colors. This copper iron sulfide crystallizes in the orthorhombic system and has a chemical composition of Cu5FeS4. It occurs in igneous, metamorphic, and sedimentary rocks across the world, making it a widespread and common ore of copper.
