Abstract
Ultrafast flash Joule heating synthesis methods and systems, and more particularly, ultrafast synthesis methods to recover metal from ores, fly ash, and bauxite residue (red mud).
Claims24
A method of recovering metal, wherein the method comprises:
- (a) mixing a material with a conductive additive to form a mixture, wherein the material is prepared from ores, fly ash, and/or bauxite residue;
- (b) applying a voltage across the mixture to recover metal from the material, wherein
- (i) the voltage is applied in one or more voltage pulses, and
- (ii) duration of each of the one or more voltage pulses is for a duration period;
- and
- (c) collecting the recovered metal, wherein the recovering and collecting of the metal comprises performing a leaching process after applying the voltage across the mixture.
