modelling and simulation of carbon-in-leach - [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

dynamic simulation of the carbon-in- pulp and carbon-in-leach

abstract - carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks which have been widely used to recover or concentrate precious metals in gold extraction plants in the carbon-in-pulp process adsorption occurs after the leaching cascade section of
