On the chloride side, the INTEC ® copper process (Everett, 1994) is well known and will not be discussed. The Outokumpu Hydrocopper Process (Hämäläinen, 2003) was developed more recently and will be reviewed here. Further review of process options for copper–gold concentrates can be found in Dunne et al. (1999). 3.1.
Overview. Pressure Oxidation (POX) is a process used to extract gold, copper, zinc, molybdenum, and uranium from refractory ore bodies. The POX process utilizes elevated temperatures (roughly 230 degrees Celsius), elevated pressures (roughly 35 bar or 510 psi), and oxygen to liberate the minerals from refractory ores.
Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm. Copper ore crushing process 1. Beneficiation methods of copper sulfide ore Copper sulfide can be divided into single copper ore, copper sulfur ore, copper-molybdenum deposit, copper nickel, carrollite …
The flotation process is most often used for copper sulfide ores due to the good floatability of most sul-fides. A flotation flowsheet usually includes a rougher ... porphyry copper ore per year (at a grade of 0.4% cop-per), applies the bulk-differential flowsheet and pro-duces copper and molybdenum concentrates. The flo-
Bornite (Cu5FeS4), covellite (CuS) and chalcocite (Cu2S) are important sources in the world, and many ore bodies also contain some malachite (CuCO3.Cu(OH)2), azurite …

This flow sheet (Fig. 5) is typical for ores with reasonable gold grade (i.e. > 1 g Au per ton ore) and have sufficiently low concentrations of iron and copper sulfide minerals that do not interfere with the processing in terms of cyanide consumption or copper dissolution. Lime is added, usually in dry quicklime form, to crushed ore via a …
