"Cominco...recently invented, patented, and is currently marketing a new environmentally friendly process for the hydrometallurgical extraction of copper from sulphide concentrates based on pressure leaching, solvent-extraction, and electrowinning. A demonstration plant capable of producing up to 500 tonnes per year of refined copper ran successfully during 1997. A gold recovery plant will be comissioned in 1998 as the process is also expected to recover gold from copper concentrate." I seem to remember hearing something a couple of years back about some firm wanting to pump leaching solution of some sort into the ground and then pump out the pregnant leach later, but I think that would guarantee ground water contamination and would never fly. This isn't what you're talking about, is it?
