What Is The Role Of Cyanide In Mining |

Cyanide is a naturally occurring chemical that is found in low concentrations throughout nature including in fruits, nuts, plants, and insects. it has been used by the mining industry to separate gold and silver particles from ore for over 120 years.gold cil & cip gold leaching process explained,cyanide 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.technologies | enviroleach technologies inc.,enviroleach technologies successfully developed a unique, cost-effective and environmentally-friendly alternative to cyanide and strong-acid based processes currently used for the extraction of precious metals from mineral ores, concentrates and e-waste.
