摘要
Process for improving recovery of copper and reducing raw material costs, from a copper-containing source by SX-EW. The process comprises the steps of mixing an acidic copper-containing PLS obtained by leaching a copper-containing source with an acidic leachant, usually sulfuric acid, with an aqueous acidic cupric chloride solution spent printed wire board etchant, to produce an acidic cupric chloride/copper sulfate-containing mixture. This mixture is subjected to SX-EW to recover the copper as copper cathode.
