It utilizes the natural propensity of minerals to dissolve in percolating water and produces a mineral-rich solution. Mineral leaching operations optimize this process through the use of chemical leaching solutions (lixiviants). Cyanide lixiviants in particular have been a standard way of processing gold for more than a century.

An overview of gold exploration in the Proterozoic Fingoe belt in Tete province, Mozambique.
Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.
