From a mineral processing perspective leaching at 70 oC may be economically desirable than leaching at 90 oC It is therefore recommended from these results that leaching at 70 C may be beneficial to save more money as leaching to higher temperatures requires a lot of energy
Bornite has a brown to copper red color on fresh surfaces that tarnishes to various iridescent shades of blue to purple in places Its striking iridescence gives it the nickname peacock copper or peacock ore Mineralogy Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite
