An Environmental Critique of In Situ Leach Mining

In Situ Leach (ISL) or Solution Mining is a third alternative mining technique, quite different to conventional open cut or underground mining and milling operations. The ISL process can be applied to the extraction of uranium, copper, silver, gold, nickel and many other metals. For an ore deposit to be amenable to ISL it must occur within
