Common Gold Ore Beneficiation Process
The quartz vein type gold ore beneficiation process is mainly cyanidation method and flotation method. The cyanidation method is a method in which gold or silver in gold or silver ore is leached by using an aqueous solution of an alkali metal cyanide as a solvent, and then gold and silver are extracted from a solution containing gold or silver.
