    摘要： A method for producing metal oxide from a metal salt selected from nickel hydroxide, cobalt hydroxide, mixed nickel-cobalt hydroxide, nickel carbonate, cobalt carbonate or mixed nickel-cobalt carbonate includes providing a mixture of the metal salt, mixing the metal salt with a binder selected from an inorganic binder or an organic binder, forming the mixture into agglomerates, and calcining the agglomerates to produce metal oxide. Another method for making metallic nickel or cobalt includes providing the above metal salt, mixing the metal salt with the above binder to form a mixture, optionally adding water, forming the mixture into agglomerates, drying the agglomerates, adding an effective reducing amount of coke and/or coal and directly reducing the dried agglomerates with an effective amount of heat to produce metallic nickel and/or cobalt. Coke particles may be added to the mixture prior to agglomeration.

    摘要： Molybdic oxide is recovered from molybdenite by a multistep process in which (A) the molybdenite is converted to soluble and insoluble molybdic oxide by pressure oxidation, (B) the insoluble molybdic oxide is converted to soluble molybdic oxide by alkaline digestion and then combined with the soluble molybdic oxide, and (C) the molybdenum values of the combined streams are extracted into an organic phase using a nonprimary amine. The extracted molybdenum values are recovered from the organic phase using aqueous ammonia to form ammonium dimolybdate (ADM) which is recovered as refined crystals from a two-step calcination process. Hallmarks of the process include one or more of economic ammonia recovery and recycle, use of ferrous sulfate to remove arsenic and/or phosphorus from the Mo-loaded aqueous ammonia strip liquor, two-stage calcination of ADM crystals, recovery of rhenium from a filtrate of the residual molybdenum precipitation stage, selenium removal from the liquid fraction from which rhenium is recovered, and caustic boil of the mother liquor from which the selenium is precipitated.

    摘要： Provided is a surface-modified metal oxide powder obtained by treating surface of a metal oxide powder, wherein a ratio (A/B) of an initial triboelectrostatic charge amount (A) at the time of one minute after dispersion of the surface-modified metal oxide powder into a ferrite carrier to a triboelectrostatic charge amount (B) with the lapse of 30 minutes in addition is in the range between 1.0 and 2.0, and the triboelectrostatic charge amount (B) after the lapse of time is in the range between −300 and +300 μC/g. The surface-modified metal oxide powder of the present invention has a weaker charging property and a better stability over time of a triboelectrostatic charge amount than a conventional one; and thus, when this powder is used as an external additive, various properties including flowability and electrical charging can be stabilized, and in addition, problems such as fogging and image deterioration can be drastically remedied without significantly deteriorating characteristics as a developer and the like.

    摘要： A process for producing metal oxide from a metal salt includes supplying a first part of the metal salt to a hydrate drier so as to indirectly heat the first part of the metal salt in the hydrate drier using a heat transfer medium from a first stage of a multi-stage indirect cooler so as to dry the first part of the metal salt in the hydrate drier and so as to control a waste gas temperature of the process. A second part of the metal salt is guided as a partial stream past the hydrate drier. The metal salt is preheated in a first preheating stage and precalcined in a second preheating stage. The metal salt and a fluidizing gas having a temperature of 150° C. or less are supplied to a fluidized bed reactor so as to calcine the metal salt to form a metal oxide product. The metal oxide product is cooled in at least one suspension heat exchanger and then in the multi-stage indirect cooler.
