Separation of copper and iron from chloride media using Cyanex 921 in kerosene

Abstract

The extraction and separation of Cu(II) and Fe(III) from HCl media using Cyanex 921 in kerosene were investigated. The effect of shaking time, aqueous phase acid concentration, Fe(III)/Cu(II) concentration, Cyanex 921 concentration, temperature and aqueous to organic phase ratio on the separation of Cu(II) and Fe(III) was studied using 0.1 mol/L Cyanex 921 in kerosene. Maximum separation was achieved from 2 mol/L HCl containing 0.001 mol/L Cu(II) and 0.005 mol/L Fe(III) with 0.1 mol/L Cyanex 921 in kerosene. Feasible separation of copper and iron was also possible from 5 mol/L HCl using 0.02 mol/L Cyanex 921.
