In Situ Leaching or Recovery Metallurgy & 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.

11/15/2019 · Leaching (metallurgy) Last updated November 15, 2019. Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts while impurity remain insoluble.These can then be washed out and processed to give the pure metal; the material left over is commonly referred to as tailings.
