This invention relates generally to novel methods and novel devices for the continuous manufacture of nanoparticles, microparticles and nanoparticle/liquid solution(s). The nanoparticles (and/or micron-sized particles) comprise a variety of possible compositions, sizes and shapes. The particles (e.g., nanoparticles) are caused to be present (e.g., created) in a liquid (e.g., water) by, for example, preferably utilizing at least one adjustable plasma (e.g., created by at least one AC and/or DC power source), which plasma communicates with at least a portion of a surface of the liquid. At least one subsequent and/or substantially simultaneous adjustable electrochemical processing technique is also preferred. Multiple adjustable plasmas and/or adjustable electrochemical processing techniques are preferred. The continuous process causes at least one liquid to flow into, through and out of at least one trough member, such liquid being processed, conditioned and/or effected in said trough member(s). Results include constituents formed in the liquid including micron-sized particles and/or nanoparticles (e.g., metallic-based nanoparticles) of novel size, shape, composition and properties present in a liquid.

An electrochemical deposition apparatus and method for the selective recovery of metal. The electrochemical deposition apparatus comprises a porous cathodic material, an anode, an inter-electrode region formed by the anode and cathode, and a gas release channel. The method may comprise passing a solution comprising a metal into a cavity, changing an oxidation state of a metal, and selectively depositing the metal onto a porous cathodic material. The electrochemical deposition apparatus may recover metal from metal feed in the form of metal hydroxides. The recovered metal may be from any source including, but not limited to, minerals, electronic waste, and black mass.

A metal recovery method includes: injecting a solution containing metal existing in an ionic state into a container where electrode plates are disposed; keeping the solution stationary relative to the electrode plates; passing a current between the electrode plates to form a sponge-like porous metal body on an electrode plate serving as a cathode; and separating the sponge-like porous metal body from the electrode. The deposited metal on the electrode does not adhere to the electrode plate, and thus can be recovered.
