Method for recovery of Gold from a Concentrated solution of Copper chloride containing Gold.

摘要

The Invention relates to a method for recovery of Gold from a Concentrated solution of Copper chloride containing Gold comprising: (a) a step of Electroplating,In an external potential is applied to an electrode or a current Reduction content in Concentrated chloride solution of Copper containing GoldSo depositing Copper on gold electrode and Optionally, (b) a step of redox replacement, in which the stage) The external potential or current reducing Applied cut or reducedAllowing the Copper deposited on the electrode to replace Vol for the Gold content in the solution, thus obtaining an electrode containing Gold.
