Solvent Extraction Isotherms. Having explained how solvent extractions can be included in a hydrometallurgical flowsheet and outlined some of the large number of interacting variables to be considered, the most basic requirement for solvent extraction design is an understanding of distribution coefficients and equilibrium isotherms.

CIL circuit is a process of continuous leaching of gold from ore to liquid and counter-current adsorption of gold from liquid to carbon particles in a series of tanks. The CIL process concentrates gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t on carbon. Although the earliest process was in South Africa in 1890, CIP/CIL was first introduced ...
