MoreCopper sulfide minerals require the use of acid and an oxidizing agent to break the mineral lattice and release Cu 2+ into solution (Sherrit, Pavlides, Weekes, 2005). Elemental copper found in nature can be leached by either oxygen or ferric ion:
MoreSep 27, 2016 The sulphide minerals are compounds of the metals with sulphur. Nearly all these minerals have a metallic luster, i.e., the peculiar shining appearance of metals, such as gold, silver, copper, lead, tin, iron, etc. They are all heavy minerals and nearly all are of economic importance. Iron Pyrites or Pyrite. FeS2.

MoreThe wettability and floatability of oxidized chalcocite, bornite, and chalcopyrite with the conditions of sodium hydrosulfide (NaHS) dosages and pHs were studied by contact angle measurements, and single and mixture mineral flotation tests. To evaluate the results of the flotation, the flotation kinetic model for copper sulfide minerals treated by NaHS was derived.
MorePyrite is the dominant sulfide in porphyry copper deposits, though it is chalcopyrite that is the most important ore mineral, along with bornite and various binary copper sulfides. In the related porphyry molybdenum deposits, it is molybdenite that dominates. The sulfides in such deposits occur as veinlets or disseminated grains in host intrusions.
MoreBornite is a copper iron sulfide mineral with a chemical composition of Cu 5 FeS 4. It occurs in igneous , metamorphic , and sedimentary rocks. Minable concentrations of bornite occur in hydrothermal veins, contact metamorphic zones, and in the enriched zone of many sulfide mineral deposits.
