Gold recovery increase in CIL circuit. Various trials have shown the potential of PIONERA BioPolymer to increase metal recovery in leaching circuits. This is especially relevant in the CIL/CIP circuits used in gold processing. The benefit of PIONERA BioPolymer is also observed in the Merrill Crowe process. A recent plant trial with an Asian gold mine showed the below results. In addition, the

This plant processes 4 million tons of ore per year with an average gold content of ounces of gold per ton of ore. Approximately 85% of the gold is recovered in the plant. From the ball and/or autogenous mill, slurry is pumped to the CIL leach tanks where lime adjusts the pH, if necessary, and it is agitated for the desired period of time.

Gold CIL process (carbon in leach) is an efficient method of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lowers the gold mining operation cost and increases gold recovery rate to a degree of 99%. It is the first choice of modern gold mining and gold beneficiation plant.

The mine produces around 450 kg of gold a month. The ores from the mine are treated in a separate stream at Kopanang Gold Plant. The Kopanang Gold Plant is a modern plant that uses millleachCIP electrowinning processes. The gold from the electrowinning process is smelted centrally in another plant situated 5 km away from Kopanang.

Typically, the carbon in pulp (CIP) or carbon in leach (CIL) process is used for gold recovery. These processes have proven to be metallurgically efficient and mechanically robust. In order to avoid gold and carbon losses due to attrition of activated carbon, low mixing power inputs and shear rates are preferred in CIP and CIL reactors.

Highlights Worldwide gold recovery on activated carbon grew from zero to almost 70% in twenty years from 1980. The stellar attributes of carbon gold plants led to complacency in the industry in designing and operating these plants. Most CIP and CIL plants are overdesigned and operated suboptimally. Optimum design criteria and operating conditions are easily determined with simple test work
learn moreElution and Carbon Reactivation Resource book
During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.

The most widely used processing method in gold production is cyanidation for carboninleach (CIL), carbonin pulp (CIP) or carbonincolumn (CIC) circuits. The gold leaching process starts with comminution. The runofmine ore is crushed and ground to a fine particle size. Water is added to the process to create a mudlike slurry.
