  • Systems and methods of efficiently recovering precious metals using an alkaline leach, ultrasound, and electrolysis
    Patent number: 10597753
    Abstract: 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.

  • Systems and methods of recovering precious metals and extracting copper from diverse substances
    Patent number: 10422019
    Abstract: Disclosed is a method for extracting a desired metal contained in electronic waste having a substrate and desired metal integrally formed with copper, the method includes (a) contacting the electronic waste with a cupric amine solution to separate the desired metal integrally formed with copper from the substrate and the copper, and (b) optionally providing ultrasound energy at a frequency ranging from 15 to 45 KHz and at a temperature ranging from 45° C. to 60° C. thereby limiting metallic oxide(s) formation at a surface of a workface; and (c) etching the copper with the cupric amine solution at a temperature ranging from 45° C. to 60° C. for between 40 to 70 hours thereby releasing the desired metal from the substrate and the copper; (d) collecting the released desired metal of step (c).
