Gold CIL Leaching Process Explained

 

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 the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp process. In the latter case leaching takes place in tanks dedicated for leaching followed by adsorption onto carbon in tanks dedicated for adsorption.

Leaching can be assimilated to the principle of preparation of tea. When we add tea in hot water, the aroma of tea will dissolve in the water and not the tea leaves. So the aromas is found in liquid form and tea leaves remains in solid form in the hot water. Thus we can separate (solid-liquid separation) tea aromas from tea leaves (filtration for example). At this stage , we have been able to extract aromas of tea from the tea leaves by changing the physical shape of the tea aromas.It is the same principle used in the leaching of gold. The gold that is in solid form in the ores turned into liquid form with cyanide in the presence of oxygen. That's the way gold is separated from the majority of its gangue. The second step is the adsorption of gold on the surface of the activated carbon. Following a natural phenomenon known around the world (positive charges attract negative charges) Gold sticking to coal. the coal loaded with gold and some impurities is then transferred to the elution where he undergoes a cold wash which removes certain impurities and then a hot wash. The solution from the hot wash is transferred to the electrolysis where pure gold is recovered.

Advantages

 

Gold Leaching( carbon in leach) process is widely used in the newly built gold leaching plants in recent years, and a lot of
plants are changing into CIL as well. Gold Leaching CIL process is suitable for the treatment of oxidized gold ore with low sulfur content and mud content. It is unsuitable for the gold ore with high-grade silver. Generally, the proportion of gold and silver should not exceed 1:5. The best conditions for CIL process in China: PH=10-12, sodium cyanide concentration is not less than 0.015%, the particle size of activated carbon is 1.0-3.35mm, the type of carbon is coconut shell activated carbon, and the slurry concentration is 40-45%. Gold Leaching Methods: flotation, carbon pulp adsorption, gravity beneficiation, and so on. These three methods of the leaching process and gold mining equipment manufacturing can be completed independently. Gravity separation and flotation are the common beneficiation methods used in gold ores, and great improvements have been made in the beneficiation technology and equipment. The mainstream gold extraction methods is generally by crusher, then comminuted by the ball mill, and then through gravity separation and flotation technology, the concentrate and tailings are extracted, chemically refined, and refined to produce gold.

Product Structure

Gold Leaching( carbon in leach) was developed from CIP( Carbon In Pulp), is characterized by less process flow, timesaver in the leaching process, thus reducing the production expenditure. Besides, advanced extraction technology improving the efficiency of gold extraction. The CIL production line is wider use than CIP in the mineral industry. Gold Processing Steps, Introduction of gold CIL production line:

A. RAW MATERIAL PREPARATION: vibration feeder- conveyor belt- crusher -Crushing- grinding- leaching-
desorption electrolysis- tailings dehydration

B. LEACHING and elimination: The thickened material is leached from eight agitators; a qualified reagent is added to the first set of agitators, and the activated carbon is lifted from the last set of agitators to the second set of agitators via an airlift to resist electric currents The activated carbon from the second set of agitators is raised to a carbon screen to obtain gold-loaded carbon, and the remaining slurry is returned to the first set of agitators And then into the tailwater treatment phase.

C. Tail Water Treatment: The tailings will be raised to pressure filter, filter cake known as tailings, through the belt conveyor and truck transport to the yard, filtrate into the circulating water tank for reuse.
D. AURIFEROUS CARBON TREATMENT: Gold powder is obtained by batch treatment of gold-containing carbon by desorption and electrolysis equipment. The dust enters the furnace and turns to the bar. The gold-containing carbon after electrolysis can be returned to the final stage of the reprocessing flowchart.
