Abstract

Systems and methods for the recovery of noble metal from noble-metal-containing material are generally described. Certain embodiments related to systems and methods in which an electric current is transported between an electrode and the noble metal of a noble-metal-containing material to dissolve at least a portion of the noble metal from the noble-metal-containing material. The dissolved noble metal can subsequently be precipitated out of solution and recovered, according to certain embodiments. Noble metals can be recovered from any suitable noble-metal-containing material, including plated and/or filled scrap materials and/or other materials.
