CIL System

Prominer can provide the complete solution for CIL (carbon in leaching) system, which is a simultaneous leach and absorption process separate from CIP (Carbon in pulp), include leaching tank, trash remove screen, carbon screen, carbon lifter, air compressor and other auxiliary equipment. It is widely used in the oxide gold cyanide leaching project.

Processing capacity: 2400tpd Diameter of Leaching tank: up to 14m


Prominer can provide the service work as below

Mineralogical analysis
Lab and pilot test
CIL system design & manufacturing by customization
On-site erection & commissioning and operation training


Our equipment with the main advantages as below

Heavy duty design
Heavy duty design optimizes leaching equipment for better process condition and higher leaching rate.
Reliable and continuous running
Easy and safe to control with low maintenance for stable operation.
Energy-saving and high-efficiency
Minimizes activated carbon attrition to prevent unnecessary costs, which causes gold and carbon losses in CIP and CIL processes.
Automation control system
Automatic control makes the whole system work continuously with low-intensity human resources.
Environmentally friendly system
Meets the environmental limits of operation with a sustainable cyanide leaching process.
Complete processing to produce gold bar
Cooperate with Elution& electro-winning system and smelting system to provide turn-key service.


Mainly used for processing the oxide type gold ore and in the gold refinery factory.

Project Cases

1500TPD gold CIL plant in Sudan

The pre-treatment and leaching adsorption adopt several sets of double impellers leaching tanks.

1500 TPD oxide gold CIL plant in Africa

The solubilized gold is adsorbed onto coarse granules of activated carbon in the tanks at the same time as the slurry flows from the fist CIL tank to the last.

2000TPD gold carbon in leaching project in Congo

The pre-treatment and leaching time is around 24 hours, and the leaching rate reaches over 96%.

3000TPD gold CIL plant in Africa

The CIL process concentrates gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t on carbon.

500 TPD Gold CIL Project in South America

The CIL process results in improved conditions for gold dissolution as a result of the lower gold tenor, albeit at a cost of lower gold-on-carbon loading.

CIL system and Air compressor

The pre-treatment and leaching time is around 24 hours, and the leaching rate reaches over 96%.

Thickener and leaching tanks

Prominer leaching tanks provides solids suspension to distribute concentrate and carbon equally around the tank.

Ball mill and cyclone cluster for gold CIL plant

Normally, the overflow from the cyclone reaches a concentration of around 40% after thickener and enters the leaching process.
