such as copper, gold, nickel and uranium from their ores by placing the ore on a pad in the form of a heap. A heap leach encompasses a level of comminution while a dump leach is run of mine (ROM), where the ore is moved directly from mining to lixiviation. In the copper industry, irrigation takes place whereby a
In electrowinning, most of the energy consumed is related to the electrical energy needed to drive the electrochemical reactions. For industrial copper and zinc electrowinning, the median specific electrical energy consumptions are 2.0 and 3.0 kWh kg −1, respectively [3, 4].This electrical energy consumption accounts for 80% of the total …

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, …
Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM. Uranium, which may be co-located with copper ore, may also be recovered as a side stream, if economical. However, in the United States this is not a general practice.
