modelling and simulation of carbon-in-leach circuits - [email protected]

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 to g/t on carbon thus playing an important role on the economics of a gold refinery in this study a
