Inventors include Kampman, Raine; Viasus Perez, Camilo Javier; Yang, Yiyi; Aprahamian, Vicken; Chhin, Danny; Auvray, Thomas; Do, Jean-Louis; Friscic, Tomislav; Lumb, Jean-Philip; Mauzeroll, Janine; and Li, Xianyao.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: A mechano-chemical process for separating at least one noble metal from a solid metal-containing component including forming a reaction mixture comprising the metal-containing component, an oxidizing agent of Formula (AE)zCnHmNpOqXa, and a reaction media comprising a protic solvent. The reaction mixture is subjected to mixing under a mechanical force being applied by acoustic waves providing an acceleration between 1 g and 100 g to the reaction mixture, thereby facilitating oxidative dissolution of the at least one noble metal from the metal-containing component. A product mixture is formed comprising an aqueous phase and an insoluble by-product being suspended in the aqueous phase. The aqueous phase includes the at least one noble metal having an oxidation state of at least 1 being present in dissolved form as a metal halide salt, a metal hydroxide salt, a metal hydroxide halide salt, a metal halide acid, or any combination thereof.
