US 2026/0209979 A1 · RECOVERY OF ENERGY CRITICAL HIGH VALUE METALS USING FUNCTIONALIZED MATERIALS

Abstract

Provided are methods for the capture of energy critical high value metals and an apparatus or system for an electrochemical approach to produce Ca- and Mg-hydroxides, silica, and leach metals into the solution phase that can be sequentially recovered. The methods entail: providing a functionalized sorbent for metal capture; recovering the metal from the metal-containing solution by contacting the functionalized sorbent with the metal-containing solution, thereby adsorbing metal ions from the metal-containing solution onto the functionalized sorbent; and desorbing the metal ions from the functionalized sorbent by contacting the functionalized sorbent with a stripping agent, thereby forming a stripped solution containing the metal ions.

A method of producing one or more metal hydroxide, oxide, and/or carbonate compounds and/or recovering one or more metals comprising:

providing an apparatus comprising an anode, a cathode, a liquid electrolyte, and optionally a separator membrane between the anode and the cathode:
providing one or more precursor compounds comprising one or more metal-bearing materials wherein the one or more precursor compounds are substantially insoluble in the liquid electrolyte and located in a first location;
applying a voltage between the anode and the cathode;
dissolving at least part of the one or more precursor compounds to form one or more soluble metal ions diffused in at least part of the liquid electrolyte as a metal-containing solution;
and
accumulating one or more metal hydroxide, oxide, and/or carbonate compounds substantially in a second location different from the first location, wherein the one or more metal hydroxide, oxide, and/or carbonate compounds are substantially insoluble in water or in the liquid electrolyte.
