AN INTRODUCTION TO COPPER EXTRACTION

An Introduction To Copper Extraction

The existing facility is able to extract a 94 grade of copper at a throughput of 25,000 tpa. However this copper is required to be further treated before it is suitable for commercial use. Due to the vast quantities of copper ore and the relative inefficiency of the Stage 1 plant, a Stage 2 upgrade has been initiated.

Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile Escondida mine and Indonesia Grasberg mine. These produce many millions of tonnes of copper ore per year.

Copper Recovery by Solvent Extraction Techniques

Copper Recovery By Solvent Extraction Techniques

Feb 02, 2017 Even so, the ratio of copper to ferric iron extracted is of the order of several hundreds to one. The level of ferric iron in the feed liquor is not as important as the pH of the solution and the concentration of LIX 64N in the organic phase. The latter is important because the extraction system operates in a counter-current fashion.
