Solvent extraction of copper(II) from concentrated leach liquors 359 extractant, which will be able to extract copper at higher acidity, but which in turn
Copper can be extracted from its ore by heating it with carbon. Impure copper is purified by electrolysis in which the anode is impure copper, the cathode is pure copper, and the electrolyte is copper sulphate solution. An alloy is a mixture of two elements, one of which is a metal.

Blue copper sulphate solution is formed 2. Add excess zinc powder in order to displace all the copper(II) ion in the solution. During the reaction, brown solid will be formed and heat is released. 3. When the solution changes from blue to colourless, add furthter sulphuric acid in order to dissolve all thr unreacted zinc powder. Hydrogen gas will be given in
The chemistry of copper is dominated by the +2 oxidation state, e.g. copper(II) complex ions, but there is a substantial chemistry of the +1

The extraction behaviour of copper(II) from acid solutions (pH 06) was studied with the new reagent 4 alkyldithiocarboxylate 3,5 dihydroxy l phenylpyrazol (HL;
Copper is extracted from its principal ore copper pyrites (CuFeS 2). The ore is concentrated by froth flotation process. The concentrated ore is roasted in a
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 it can be used on ores with as little as 0.1

Extraction isotherm for copper indicates that a total of four stages are required for complete extraction of copper whereas, complete extraction of zinc could be achieved in three stages using the phase ratio of 1.11 and 1.91 respectively (Figure 5 and Figure 6).
This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction of
