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.
