In Situ Leaching or Recovery Metallurgy amp; Mineral

In situ leaching (ISL), also known as in situ recovery, is a low capital cost method of extracting uranium, copper or potash from suitable deposits. A suitable deposit is one where the commodity is located in saturated permeable horizons or distinctive geological areas that are bounded above and below by impermeable strata.
