3. Copper sulfate solution is collected in the pregnant leach pond then pumped to the solvent extraction plant. The solvent extraction phase of treatment occurs in two stages. During the initial phase an organic solvent is used to recover copper ions contained in the pregnant leach solution, exchanging them with hydrogen ions in the acid.
As the acid trickles through the ore, it combines with the copper, producing a weak copper sulfate solution. The so-called 'pregnant' leach solution (or pregnant liquor) is then processed using a hydrometallurgical process known as solvent extraction and electro-winning (or SX-EW).

Copper Leaching Practices. For centuries small amounts of copper have been recovered from acid mine-drainage waters. In recent years, the expansion of copper-bearing waste dump leaching for copper recovery has established a technological basis that is rapidly converting the art of copper leaching into a science.
The resulting "pregnant" leach solution of sulfuric acid and copper sulfate is collected in a small pool. The copper compound can now be seen at concentrations of between 60-70%. The second step is solvent extraction, in which two immiscible (un-mixing) liquids are stirred and allowed to separate, causing the cooper to move from one liquid ...

The copper sulfate electrodes (Cu/CuSO 4) are the favorite reference for pipeline corrosion control since they are very stable and rugged for field use (Fig. 1.6).Most standard CP criteria to help determine adequate CP are related directly to the Cu/CuSO 2.Cu/CuSO 2 is traditionally used on soils and in fresh waters. Use in chloride environments and other contaminates can cause the potential ...

The time necessary for efficient activation by copper sulfate, hydrate or basic carbonate is only about one minute, although to provide good mixing or stirring it is probably wise in any flotation machine to allow as much as five minutes.
into favor. Many methods employ copper sulfate. Titanium oxide and copper sulfate in combination have been found to be more effective than copper sulfate alone. Selenium is fre-quently used. Commercially prepared mixtures of potassium sulfate and a catalyst are available from laboratory chemical suppliers. Bulk custom mixtures are also available.
The copper plate produced in this way, called "electrolytic copper", is of extremely high quality and can be used to make electrical products.Crude copper (containing 99% copper) was made into thick plate as anode, pure copper as cathode, and the mixture of sulfuric acid and copper sulfate as electrolyte.
This experiment involves the extraction of copper from an aqueous copper sulfate solution using a solution of LIX (a copper complexing agent) in kerosine. Runs will be made at different feed and stirring rates, in some cases under conditions in which the streams leaving the mixer-settler are in equilibrium.
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
