Copper Recovery by Solvent Extraction Techniques

Feb 02, 2017 The capital cost of a solvent extraction plant depends on the throughput of leach liquor and not simply on the copper production rate.

market, i.e.supply of concentrate vs smelting capacity. When copper prices are low, naturally supply of concentrate dries up fairly quickly, whereas smelters keep going, thus there is a rough relationship as one might expect between copper prices and treatment charges. Figure 3 presents the historical copper prices and TC/RCs from 1986 to present.
