  • Publication number: 20120067737
    Abstract: A method and apparatus for producing particles from a starting material, which includes at least one electrochemically-reactive material, with metal counter ions is disclosed. The starting material can be a bulk material, a virgin material, a purified, recovered material, and/or an industrial waste. The electrochemical-reactive material can be recovered in particle form, including microparticles and/or nanoparticles. The recovered material can be substantially pure electrochemically-reactive material or an alloy of the electrochemically-reactive material. In some embodiments, one or more electrochemically-reactive materials can be selectively recovered from the starting material.
