بيت /Copper Recovery By Solvent Extraction Flow Chart
The present invention relates generally to a process for recovering copper and/or other metal values from a metalbearing ore, concentrate, or other metalbearing material using pressure leaching and direct electrowinning. More particularly, the present invention relates to a substantially acidautogenous process for recovering copper from chalcopyritecontaining ore using pressure leaching ...

This solution, known as pregnant liquor, is recovered and then contacted with an organic solvent, referred to as the extractant, in the solvent extraction stage (SX). Here the copper is extracted away from the aqueous phase leaving behind most of the impurities that were in the leach solution. Since the copper ion is exchanged for hydrogen ion ...

25/04/2007 · SXEW Kchnology is a two step process. First, the metal in the pregnant (leach) solution is extracted using an organic reagent (solvent) and stripped from the solvent in a purified state using concentrated acid. Second, the metal is recovered from the acid solution as high purity hode copper by electrowinning.
