Jan 02, 2013 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. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to ...

Apr 12, 2019 3. Factor Affecting Gold Leaching: Cyanide Agent Dosage. Gold is a kind of inactive metal, which can cause complexation reaction with cyanogen (CN-) under the action of oxygen in the cyanide leaching process, and then results in Au (CN) 2-. Therefore, cyanide agent dosage is one of the key factors determining the gold dissolution.

Sep 04, 2020 If excessive sodium cyanide or air is added during the leaching process, it will not increase the leaching rate of gold and cause waste. Therefore, in the gold leaching process, it is often necessary to analyze and control the free cyanide and the oxygen content in the solution to keep the ratio of the two at about 6. 4.
