Estimating the term…
The present invention relates to a precious metal leaching method by electrogenerated chlorine and its apparatus, more precisely, the electroleaching apparatus is composed of two reaction chambers at both sides (right and left) which is divided by central separation membrane; one of the reaction chamber is leaching chamber equipped with chlorine leaching-stable electrode for the electrogeneration of chlorine and stirrer for solution stirring and the other reaction chamber is reduction chamber equipped with electrode used for electrolytic recovery of some parts or entire compounds of leached precious metal, and the apparatus can additionally include separator/purifier for quick recovery of targeted precious metal, if necessary. The present invention provides a very simple leaching method and an apparatus thereof which has high leaching efficiency and enables the recovery of leached precious metal.
