SYSTEMS AND METHODS OF EFFICIENTLY RECOVERING PRECIOUS METALS USING AN ALKALINE LEACH, ULTRASOUND, AND ELECTROLYSIS

摘要

The subject matter described herein includes a method for extracting a desired metal from a substance. The method includes contacting the substance with an alkaline leach to separate the desired metal from the substance, providing ultrasound energy and anodic current on a work face of the substance, etching the substance with the alkaline leach, thereby releasing the desired metal from the substance, and collecting the released desired metal.
