  • Patent number: 8557019
    Abstract: 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.
