Copper Recovery by Solvent Extraction Techniques

2017-2-2  What solvent extraction offered was the opportunity to produce cathode copper directly from the leach liquor on the same site as the leaching operation. This gave advantages to both the large producer who would not have to consider extra smelting capacity when extending his leach operations and to the small producer who would be able to produce a finished grade of copper.
