Adsorption of copper cyanide complexes on to activated carbon in the adsorption stage for gold recovery follows the trend show below: Cu(CN)2– > Cu(CN)32‐ > Cu(CN)43‐ (4) The predominance of the Cu(CN)2– complex under cyanide deficient conditions is yet another reason to maintain excess free cyanide in the leach.
All over the world, highgrade copper deposits are rare; lowgrade ore bodies are common. Beneficiating these lowgrade resources is expensive. Productive mines and concentrators cost billions of dollars to capitalize, and many years to develop. Today, costs are increasing for .
environmental regulations, the copper industry was obliged to transform its SO2 into sulfuric acid. For each tonne copper, 3 tonnes acid are produced. If there is no local need for the acid,, for leaching oxide ores, then the acid has to be marketed. Shipping a corrosive liquid for long distances is not an easy task it is risky and ...
2. Leaching. The ore is treated with dilute sulphuric acid. This trickles slowly through the ore dissolving copper to form copper sulphate. The copper is recovered by electrolytic refining. Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off
leaching of highgrade copper oxide ore followed by EW of copper from the leach solution, produced low quality copper cathode at relatively high cost. In 1968 the tonnage of highgrade oxide ores was decreasing and vat leaching was on the decline.

At a blend of 70% sulphide ore and 30% oxide ore, the rougher scavenger copper recovery was as high as %. The copper recovery from the blended ore using a mixture of collectors was shown to be superior to the recovery obtained using only xanthate after controlled potential sulphidisation. 2008 Elsevier Ltd.
Synopsis. Although it is clear that flotation has become the conventional way for beneficiating metal sulphide ores and will remain so as long as grade is sufficient to bear the cost, other methods have to be taken into consideration.
Flotation of Oxide Copper and Copper Cobalt Ores . This method is the most commonly used in beneficiation if oxide copperbearing ore. The reagent schemes used to treat oxide copper ores, mixed copper sulphide oxide ores and oxide copper cobalt ores varies from one ore type to the next, mainly by type of collector and sulphidizer used.

The usual mode of operation is reducing smelting, which yields two main products. Sulfide ores are used to produce a matte (40 – 50 wt % Cu) and a disposal slag (ca. wt % Cu). In contrast, oxide ores are processed directly to impure black copper ( 95 wt % Cu) and to a copperrich slag.
