Copper minerals generally occur as oxides or sulfides. These require different treatments for extraction of the metal. The oxides are exposed to acid in a heap leach; this liberates the copper ions and the resulting solution is then sent to the solvent extraction (SX) process followed by electrowinning (EW) of the copper.

With Flottweg Tricanter® centrifuges, copper mines can recover organic from crud and reuse it in their solvent extraction processes. The solvent extraction (SX) process is a hydrometallurgical procedure in which metals, such as copper, platinum, gold, cobalt, nickel, zinc, or uranium, are recovered through the use of organic extractants.

The Nifty Copper Mine is located on the western edge of the Great Sandy Desert in the north-eastern Pilbara region of Western Australia, approximately 350 km southeast of Port Hedland. Nifty was initially discovered by WMC in 1981 and commenced operation in 1993 as an open pit oxide copper mine with processing via heap leaching and solvent ...

Solvent extraction of metals remains a core part of Cytec's business, and the company provides highly selective reagents primarily for copper, cobalt, nickel and several rare metals. These extractants provide plants with enhanced kinetics, productivity and throughput.

Plans have now been announced for the construction of the largest solvent extraction plant in the world to be designed by The Power-Gas Corporation for Nchanga Consolidated Copper Mines Ltd, at Chingola in Zambia. This plant will have a throughput of 12,000 gallons per minute of leach liquor with a copper content in excess of 60,000 annual tons.
