  • Publication number: 20260078467
    Abstract: Enriched metal concentrates and metal products are produced at standard temperature and pressure via sequential treatment of metal concentrates with chemical reducers such as vanadium (V(II)) and chromium (Cr(II)) and chemical oxidizers (Ce(IV)). Naturally occurring ores such as pentlandite, pyrrhotite, chalcopyrite, etc. include concentrations of iron and sulfur that are preferentially leached via reaction with the chemical reducers. The resulting products are enriched for target metals, such as nickel, and can be further reacted with chemical oxidizers to recover metal leachates. Additional ferric iron ion leaching can isolate high concentrations of copper metal products as well. Lower-quality minerals can be converted to higher-quality concentrates as demand for higher-quality feedstocks increases yet the available of those feedstocks decreases.

  • Patent number: 8941387
    Abstract: An electrical waveform is received over an electrical power line. A plurality of nominal electrical parameters are determined for the electrical power network and the plurality of nominal electrical parameters are associated with a state of the electrical power network in the absence of at least one transitory electrical fault in the network. Subsequently, a plurality of electrical parameters of the electrical waveform are sampled when the at least one transitory electrical fault exists in the network. A plurality of inductances are determined based at least in part upon a comparison of the nominal electrical parameters and the plurality of sampled electrical parameters. The plurality of inductances are representative of inductances present in the network when the at least one transitory electrical fault exists in the network. The plurality of inductances are analyzed to determine a distance and/or direction to the at least one electrical fault.
