bornite mineral processing

Bornite - Wikipedia

Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite. Chalcopyrite and bornite are both typically replaced by chalcocite and covellite in the supergene enrichment zone of copper deposits. Bornite is also found as disseminations in mafic igneous rocks, in contact metamorphic skarn deposits, in pegmatites and in ...

Bornite mineral Britannica

Bornite, a copper-ore mineral, copper and iron sulfide (Cu 5 FeS 4). Typical occurrences are found in Mount Lyell, Tasmania; Chile; Peru; and Butte, Mont., U.S. Bornite, one of the common copper minerals, forms isometric crystals but is seldom found in these forms. It alters readily upon weathering to chalcocite and other copper minerals. For detailed physical properties, see sulfide mineral ...

THE MECHANISM OF BORNITE LEACHING: INSIGHTS FROM ...

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. Moreover, smaller particle size range of -53 + 38 µm produced a higher recovery than -355 + 150 µm, the difference ...
