Apparatus and methods for lithium, calcium, and magnesium extraction

A method of selectively extracting one or more target metals from a mixture, the method comprising:

• combining, in a leaching tank, a solid substrate comprising the one or more target metals a solvent and to thereby form the mixture;
• applying sonic energy to the mixture to thereby separate the one or more target metals from non-target materials;
• outputting the one or more target metals in a target metal-rich stream.

An assembly comprising:

• a leaching tank defining an interior chamber having one or more inlets and one or more outlets, wherein the leaching tank is configured to receive through the one or more inlets a mixture comprising a substrate having one or more target metals and a solvent;
• and
• an acoustic probe positioned within the interior chamber and configured to provide acoustic energy to the mixture, an acoustic plate in contact with the leaching tank and configured to provide acoustic energy to the mixture, or both the sonic probe and the sonic plate, and including flowing/suspended acoustic probes.
