  • Patent number: 8137654
    Abstract: Provided is a roasting method capable of reducing both C and S components in minerals down to 0.5% or less, respectively, and securing a yield ratio of 90% or more for the Mo component. In a rotary kiln 7, a V, Mo and Ni containing material containing C and S components is subjected to oxidizing roasting to remove the C and S components from the material before reducing the material by means of a reducing agent in order to recover valuable metals composed of V, Mo and Ni. The rotary kiln is equipped with a burner 11 disposed on a material charge side 8a of the roasting furnace 8 to which the material is charged. In the roasting furnace, a direction along which the material moves and a flow of oxygen-containing gas introduced into the roasting furnace 8 are set to be parallel with each other.

  • Patent number: 8110173
    Abstract: A method is disclosed for fabrication of NiO nanoparticles and NiO chip-like nanoflakes by solvothermal technique. Mixed organic alcohols were used as solvent to make a homogenous solution from a nickel containing salt (or complex) for production of NiO nanoparticles and chip-like nanoflakes. The solution was heated in a sealed flask sitting inside a warm furnace. The precipitate was filtered, rinsed, dried and calcined to produce nanoparticles or nanoflakes. The size of the particles was controllable by heating time and temperature. Similar procedures were used for production of both nanostructures except hydrogen peroxide addition to the initial solution for NiO chip-like nanoflakes fabrication.

  • Patent number: 8066969
    Abstract: This invention relates, in general, to a method of producing magnetic oxide nanoparticles or metal oxide nanoparticles and, more particularly, to a method of producing magnetic or metal oxide nanoparticles, which comprises (1) adding a magnetic or metal precursor to a surfactant or a solvent containing the surfactant to produce a mixed solution, (2) heating the mixed solution to 50-6001 C to decompose the magnetic or metal precursor by heating so as to form the magnetic or metal oxide nanoparticles, and (3) separating the magnetic or metal oxide nanoparticles. Since the method is achieved through a simple process without using an oxidizing agent or a reducing agent, it is possible to simply mass-produce uniform magnetic or metal oxide nanoparticles having desired sizes compared to the conventional method.
