网页2015年11月1日As the slurry passes through the circuit, gold continuously leaches in the cyanide solution. Sufficient residence time is provided in each tank to facilitate the leaching. Carbon particles are suspended in the tanks to simultaneously adsorb gold from cyanide solution. Screens are installed in each tank to prevent carbon transfer along with the ore.

Modelling and Simulation of Carbon-in-Leach Circuits CORE
网页A CIL circuit is a process of continuous leaching of gold from ore to liquid using a counter-current adsorption of gold from liquid to carbon particles in a series of tanks. It concentrates gold from 2.5-3.5 g/t in ore to 10000 to 15000 g/t on carbon, thus playing an important role on the economics of a gold refinery.

Carbon In Leach Process and Optimization
网页2021年2月8日For CIL, carbon must be added to crude/solvent tincture and agitated for 20-30 minutes. Carbon is added to the tincture in 3-4 portions to promote better adsorption. This is because carbon's affinity to certain particles changes as the carbon pores are used up. Adding fresh carbon in stages reduces the overall dosage necessary and ultimately

Leach circuit residence time testing Hydrometallurgy: Leaching
网页The efficiency of the leaching process greatly depends on the flow structure created by mechanical agitation (in some cases air agitation) in the leaching tanks. Residence time distribution (RTD) measurement was conducted in the CIL section of a gold processing plant in order to determine the flow structure in the first tank using the 131 I radioactive tracer.
