Copper extraction Wikipedia

To improve the process efficiency, lime is used to raise the pH of the water bath, causing the collector to ionize more and to preferentially bond to chalcopyrite (CuFeS 2) and avoid the pyrite (FeS 2). Iron exists in both primary zone minerals. Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29%

copper extraction and purification chemguide

The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. Getting copper from chalcopyrite, CuFeS 2. Chalcopyrite (also known as copper pyrites) and similar sulphide ores are the commonest ores of copper.

01/01/1999  The effect of the higher temperature on chalcopyrite leaching was so pronounced that copper leached faster from the chalcopyrite ore used as support rock at 70 ~ than from the chalcopyrite concentrate at 35 ~ (data not shown). Rapid leaching of chalcopyrite with thermophiles has been obtained in stirred reactors [15, 28, 29], but only at low pulp densities. Boon [2] has

Copper Ore Processing Methods

11/04/2017  The flotation process, which was responsible for the almost complete change in equipment, has also undergone marked changes since its introduction in large-capacity concentrators. Flotation, when first introduced between 1913 and 1916, was used primarily to reduce losses of copper in the fine tailings of gravity plants. From an accessory to gravity methods, flotation very rapidly became a

Separation Process of Chalcopyrite, Galenite, Sphalerite

Under relatively coarse fineness, chalcopyrite and pyrite can be fully dissociated, and separated. Separation Turn: chalcopyrite first, pyrite second. 1.2 Bulk Flotation: This method is suitable for the combination of chalcopyrite and pyrite in the ore.

Comparative study on the selective chalcopyrite

Chalcopyrite is a refractory ore, but in the presence of molybdenite its dissolution is sped up due to the formation of a galvanic couple. According to the electrochemical tests carried out, the decomposition potential for chalcopyrite and molybdenite is +730 mV and +925 mV, respectively. The latter potential is very high and is virtually impossible to reach using the bioleaching processes. This is the reason why
