Sep 01, 2020  1. Introduction. Copper-sulfide minerals, such as chalcocite (Cu 2 S), bornite (Cu 5 FeS 4), and chalcopyrite (CuFeS 2) are important copper resources from copper mines (Fullston et al., 1999).Flotation tends to be used to recover and concentrate these minerals. Flotation is a separation method that uses the surface wettability property (hydrophobicity and hydrophilicity).

Sep 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.

What is Sulfide Mining? Mining Action Group

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water ...

Copper Sulfide - an overview ScienceDirect Topics

Copper sulfide minerals require the use of acid and an oxidizing agent to break the mineral lattice and release Cu2+ into solution ( Sherrit, Pavlides, Weekes, 2005 ). Elemental copper found in nature can be leached by either oxygen or ferric ion: (15.6a) Metallic copper: Cu + 0.5O 2 + H 2SO4 → Cu2 + + SO2 − 4 + H 2O.
