Recover Metal from Acid Leach Processing of Arsenic Rich

Those bench-scale studios detailed the effects of waste composition, pulp density, leach time, and temperature on the sulfuric-acid leaching of an arsenic-bearing material. Sulfuric acid leaching was used because sulfide mineral processors generally produce sulfuric acid as a byproduct, thus providing a cheap source of raw material.

Chemical leaching

Chemical leaching technology can be used to recover valuable critical raw material from industrial mixed waste materials (e.g. sludges, slags, ashes). The concept will integrate innovative environmental friendly chemical leaching procedures that allow for the valorisation of both valuable critical raw materials and matrix materials of the waste material.

Toxicity Characteristic Leaching Procedure (TCLP)

The Toxicity Characteristic Leaching Procedure (TCLP) is a preliminary step in determining non-volatile contaminants present in solids and wastes. The solid sample is extracted with an amount of extraction fluid equal to 20 times the weight of the solid phase. The extraction fluid for TCLP is a function of the alkalinity of the solid waste.
