The Toquepala copper mine operation includes an acid leaching system for copper extraction where ore is sprayed with a sulfuric acid solution. This acid and copper rich solution, called PLS (Pond Liquid Solution) is collected in ponds and then pumped back to the

(PLS) Pregnant Leach Solution pondtemperature

The extraction kinetics are potentially going to suffer because for the extractant to coordinate a copper ion out of your PLS, there is an activation energy involved (rather low, but still). At colder temperatures, that means that it will take longer to reach equilibrium of copper in the organic vs. aqueous phases.

Improved Copper/Iron Selectivity in Solvent Extraction

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.

60 Centuries of Copper: Its Effect on Copper Mining

The cost of copper, in those days, was very great. In 1714 cake copper, unrefined, fetched £100 per ton, and plates as they came from the battery works cost £140 to £150 per ton. In 1694 Swedish copper, which was then regarded as high quality, cost £168 per ton. These figures, currency for currency, far exceed modern prices.
