Copper Mining and Extraction Sulfide Ores
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

Extraction of copper from mining residues by rhamnolipids ...
A minimum volume of 10mL rhamnolipid of 2% concentration for 1 g of ore was required to extract about 28% of copper from the ore. Although better results are also possible with higher concentrations of rhamnolipid, the solution becomes very viscous as well. Adding 1% NaOH to the solution dramatically improved the extraction up to 42% in 6 days.
