FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

The disadvantage of the process is the toxicity of cyanide to human and animal life, and the negative perception this has created in the public domain. Despite its toxicity, the gold mining industry has worked with cyanide for over 100 years with remarkably few human fatalities due to cyanide ingestion, and with minimal impact on the environment.

Gold CIL & CIP Gold Leaching Process Explained CCD

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

contacting the carbon with a solution of sodium cyanide (0.1 to 2% by mass) and sodium hydroxide (0.1 to 2% by mass) at high temperatures (90–120°C). This results in the reversal of the adsorption process with most of the gold desorbing from the carbon back into solution. This produces a small volume of solution with a high gold concentration.
