Hydrometallurgical techniques are in industrial operation to extract copper from oxide and secondary sulfide ores, but the treatment of chalcopyrite remains challenging. Chalcopyrite is the most refractory copper mineral. Harsh conditions (highly acidic solutions, high pressure and temperature, or thermal and chemical pretreatments) are required.
The separation of chalcocite (Cu2 S) and heazlewoodite (Ni 3 S 2) from high nickel matte can be achieved by maintaining the proper pH and pulp potential while using xanthates as collectors.
Copper ores containing chalcopyrite can . % copper-in-concentrate, as chalcocite . Separation of copper from chalcopyrite using hydrochloric acid . . a wet method for the lixivation of copper from chalcopyrite. In the separation . grade copper ore such as chalcocite . as by solvent extraction or .
In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3as oxi- dizing agent and ethylene glycol (EG) as organic solvent).
Stage 3: Roasting At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite – CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.

The remaining 10 percent was present as native copper. ... (large white grains) and taken on a rounded appearance. This facilitates copper separation from the slag during smelting by increasing the ...
May 04, 2020· In this new SIM² KU Leuven study, a solvometallurgical process for the extraction of copper from sulphidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidising agent and ethylene glycol (EG) as organic solvent) (see Figure 1). Figure 1.
Solvometallurgical process for extraction of copper from . Extraction of copper from sufidic ores either by pyrometallurgy or hydrometallurgy has various limitations. In this study a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite bornite chalcocite .
fully for the extraction of copper from secondary sulphide minerals such as chalcocite at a number of operations worldwide. However, heap bioleaching of the refractory primary copper sulphide chalcopyrite, has yet to be imple-mented at commercial scale (Watling, 2006). The predominant metal-sulfide-dissolving microor-
The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of .

In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant ...
In fact, an alternative copper extraction route from mixed sulphide ores, chalcopyrite and chalcocite using mesophilic biomass consortium at 33.3 °C and ferric leaching process were attempted. Bioleaching experiments were settled with a fraction size of −75+53 µm. Bacteria were used as the catalyst. A copper yield of 65.50% was obtained.
Copper ore divides into ore sulfide,ore oxide and mixing ore according to its oxide rate . The main process for copper ore is flotation, for refractory mixed copper ore and refractory oxide ore, normally use hydrometallurgy process .It is a high technological .
