Leaching Processes For Inorganic and Organic Materials
Leaching is extensively used in metal processing industries. The useful metal may occur in mixtures with very large amounts of undesirable constituents, and leaching is used to remove the metals as soluble salts. The use of acids is prevalent in the metal processing industry, Sulfates are normally used to remove metals from the solid phase, these produce harmful environmental byproducts such as sulfates.
