Bornite is a popular and fast-selling mineral specimen at museums, mineral shows, and tourist shops. However, some material sold as "peacock ore" has a tarnish with spectacular colors - greatly exceeding what is expected on bornite. This material is frequently chalcopyrite that has been intentionally tarnished with acid.

A thermodynamic and kinetic model is proposed to explain the formation of bornite, chalcopyrite, and magnetite during partial roasting of enargite-containing copper concentrates. The proposed mechanism involves solid–solid–gas and solid–gas reactions between chalcocite, pyrrhotite, gaseous sulfur, and oxygen. Bornite formation could be explained through a …

How To Clean Peacock Ore? | Cleanestor
Bornite is an important ore mineral because it contains nearly 63% Copper when pure. However, it rarely occurs naturally as pure bornite; it usually contains some Chalcopyrite which lowers the overall Copper content to around 30%. This means that bornite must be concentrated before it can be processed into Copper metal or ore compounds.
