The blister copper produced by this process is 99% pure copper. The name ''blister'' copper comes from the fact that this final process produces bubbles of sulfur dioxide on the surface of the copper. The blister copper is cast into anodes ready for electrolytic refining. The anode casting turntable moves slowly round.

First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SXEW (solvent extraction/electrowinning).

The first element to extract by solvent extraction is copper. For the solvent extraction of copper, different selective extraction agents are available. Two agents were tested, LIX‐860‐IC and LIX‐860N‐IC, both produced by BASF. As shown in Fig. 4, LIX‐860‐IC has a high selectivity and high recovery for copper for the investigated pH range. No significant differences are observed ...

In the electrolytic process, copper anodes and starting sheets are immersed in an electrolytic solution made up of copper sulfate and sulfuric acid. An electric current is passed through the solution, and copper from the positively charged anode is deposited in a pure form on the negatively charged starting sheet, which acts as a cathode.

The process is called phytomining and it can also be used to extract metals from contaminated land. Brassicas (the cabbage family) can extract metals including cadmium, cobalt and nickel. Copper can also be extracted by displacement from a copper salt solution using scrap iron. Pure copper (99·99%) is needed for good electrical conductivity.

· Currently the extraction of copper is performed using a pyrometallurgical process that involves the use of electricity as well as coal, both of which are expensive. The use of fossil fuels in extraction produces carbon dioxide which contributes to global warming. The other method used is solvent extraction followed by electrowinning (SXEW). This method is applied in Zambia, the .

The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.

Copper can be extracted from nonsulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper (II) sulphate solution. Concentration of the copper (II) sulphate solution by solvent extraction.
