generator, electrical energy and copper refining/winning were united in the first electrolytic copper refinery in 1869. A plant for large-scale copper electrowinning from leach solutions was first built in 1917. 1 Since then, although the basic prin-ciples and fundamental theories of copper refining/winning have remained

plant. One of the principal reasons for doing live harvesting is to protect the anodes and cathodes from damage if no current is flowing. In copper electro-refining the copper anode and copper deposit on the cathode leach very slowly in electrolyte, and do not set up a galvanic couple. In electrowinning however

The electrowinning capital cost is the same for each plant and is based on a copper production of 27.2 tonnes/day. A unit capital cost of $945/Ann. tonne, which is about midway between the high and the low unit costs for the case studies shown in Table 2, was used.

SX-EW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid. Folowing leaching, the pregnant leaching solution is transported via a drainage system to the next stage. In an SX-EW reactor, the first process to take place is solvent extraction, which involves …
