Contact. The nature and chemistry of an ore deposit determine the processing method used in gold production. There are many processing techniques for gold ore. The most common is cyanidation in carbon-in-leach (CIL), carbon-in-pulp (CIP) or carbon-in-column (CIC) circuits. Neles™ has a wide range of valves ideal for CIL, CIP, and CIC processing.

The gravity/flotation flowsheet with cyanidation of the respective concentrates recovered between 30 and 77% of the gold in feed, with an average of about 59 percent across all eight lithology composites. Whole-of-ore CIL extracted between 28 and 79 percent of the gold in feed, with an average of about 61 percent.

CIL Processing Flow. CIL circuit is a process of continuous leaching of gold from ore to liquid and counter-current adsorption of gold from liquid to carbon particles in a series of tanks. The CIL process is complex, and the CIL circuit holds the key to profitability in the gold extraction process. Here is a schematic of the CIL process.
