ELECTROLYTIC EXTRACTION OF COPPER FROM BATH OF SULPHUROUS ACID |
摘要 |
<p>A process of precipitating Chevreul salt from a solution comprising copper dissolved in sulphurous acid including the steps of contacting the solution with a pair of electrodes, the anode preferably being copper, and applying a potential difference across the electrodes effective to cause precipitation of the Chevreul salt. The potential difference is preferably such that the cathode potential is between a few millivolts and about 250 millivolts. The copper containing solution is preferably a copper rich leach solution resulting from the sulphurous acid leaching of a copper-containing oxidic ore.</p> |
