    Abstract: Disclosed is an α-phase nickel hydroxide and a preparation method and use thereof. The method for preparing an α-phase nickel hydroxide comprises the following steps: subjecting a biomass calcium source to a calcination to obtain a porous calcium oxide; under a protective atmosphere, mixing the porous calcium oxide with a first methanol-ethanol solvent to obtain a calcium oxide heterogeneous solution; under a protective atmosphere, mixing the calcium oxide heterogeneous solution with a nickel source homogeneous solution to obtain a mixture, and subjecting the mixture to a coprecipitation to obtain a nickel calcium hydroxide precursor, wherein the nickel source homogeneous solution is prepared with a nickel source containing crystal water as a solute and a second methanol-ethanol solvent as a solvent; and subjecting the nickel calcium hydroxide precursor to a calcium hydroxide removal treatment to obtain the α-phase nickel hydroxide.

    Abstract: A process is disclosed for separation and recovery of vanadium, molybdenum, iron, tungsten, cobalt and nickel from alumina-based materials, mattes, ores, manufacturing by-products and waste. These elements are oxidized. The oxides are reacted with gaseous HCl to form volatile chloride-bearing compounds that subsequently sublimate. The volatile compounds are condensed in a downward-stepped thermal gradient that allows collection of moderate to high purity compounds of individual elements with exception of a nickel-cobalt co-condensate. Nickel is separated from cobalt by precipitation of nickel chloride from concentrated HCl pressurized with gaseous HCl.

    Abstract: The present invention is directed to processing techniques and systems of metal fluoride based material, including but not limited to nickel difluoride, copper difluoride, manganese fluoride, chromium fluoride, bismuth fluoride, iron trifluoride, iron difluoride, iron oxyfluoride, metal doped iron fluorides, e.g., FexM1-xFy (M=metals, which can be Co, Ni, Cu, Cr, Mn, Bi and Ti) materials. An exemplary implementation involves mixing a first compound comprising a metal material, nitrogen, and oxygen to a second compound comprising hydrogen fluoride. The mixed compound is milled to form metal fluoride precursor and a certain byproduct. The byproduct is removed, and the metal fluoride precursor is treated to form iron trifluoride product. There are other embodiments as well.
