  • Cyanide Use in Gold Mining Earthworks

    Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold Partially due to cyanide, modern mines are much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste More than 20 tons of mine waste are generated to produce enough gold for a typical ring What are the dangers of using cyanide?Traditional gold processing methods generally use the toxic chemicals cyanide or mercury as reagents to extract gold particles from ore, exposing miners and the environment to toxic waste and gases In contrast, Clean Mining offers an environmentallysound gold processing technology that uses an inorganic compound, thiosulphate, in the place of toxic chemicalsHow to set up an ecofriendly gold processing plantCyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon CIL stands for carboninleach This is a gold extraction process called cyanidation where carbon is added toGold CIL & CIP Gold Leaching Process Explained CCD
