The Process Design Of Gold Leaching And Carbon

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

Improving The Process Performance Of Gold Cyanide

In the gold mining industry today cyanide leaching is the prevailing method for solubilizing and recovering gold Most of the new gold that is mined each year is processed via adsorption of gold cyanide onto activated carbon (Fleming et al 2011) Typically the carbon in pulp (CIP) or carbon in leach (CIL) process is used for gold recovery These
