Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW solvent extractionelectrowinning.
Most of the copper ores mined today are oxide or sulfide ores. extraction of sulfide ores is covered in more detail in copper mining and extraction sulfide ores 1114, but is introduced here because an important by-product of this process is used for the extraction of oxide ores. pyroprocessing sulfide ores provides acid for leaching
