The whole process takes place on top of an impermeable, double or triple layered liner to collect all of the valuable gold and prevent the escape of dangerous CN. POLITICAL HISTORY OF CYANIDE LEACHING In 1996, environmental groups headed by MEIC from Missoula launched an attack on mining through the initiative process.
Extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. Gold dissolves in aqua regia, a mixture of hydrochloric and nitric acids, and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from lowgrade ore.
