  • Patent number: 8574540
    Abstract: A method for producing prefluxed metal oxide from a metal salt selected from nickel hydroxide, cobalt hydroxide, mixed nickel-cobalt hydroxide, nickel carbonate, cobalt carbonate, mixed nickel-cobalt carbonate and combinations thereof includes providing a mixture of at least one slag making oxide and a metal salt selected from the group consisting of nickel hydroxide, cobalt hydroxide, mixed nickel-cobalt hydroxide, nickel carbonate, cobalt carbonate, mixed nickel-cobalt carbonate and combinations thereof, blending with a binder, blending in a flux additive to form a slag-making mixture, forming the slag-making mixture into prefluxed agglomerates, and calcining the prefluxed agglomerates to produce a prefluxed metal oxide. An agglomerate is provided which includes a metal salt selected from nickel hydroxide, cobalt hydroxide, mixed nickel-cobalt hydroxide, nickel carbonate, cobalt carbonate, mixed nickel-cobalt carbonate and combinations thereof, a slag making oxide, and a flux additive.

  • 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.

  • Patent number: 7033555
    Abstract: A low temperature contaminant limiting process for lithiating hydroxides and forming lithiated metal oxides of suitable crystalinity in-situ. M(OH)2 is added to an aqueous solution of LiOH. An oxidant is introduced into the solution which is heated below about 150° C. and, if necessary, agitated. M may be selected from cobalt, nickel and manganese. The resultant LiMO2 becomes crystallized in-situ and is subsequently removed.

  • Patent number: 5853657
    Abstract: A pyrometallurgical vessel suitable for continuous or semicontinuous smelting and/or conversion of molten base metal sulfide feed materials. The top blown, bottom stirred vessel includes oxidizing gas lances and feed pipes directing their respective contents directly or indirectly into bath eyes opened up in the molten bath by gas injected through porous plugs disposed at the base of the vessel. Low space velocities in the vessel result in reduced dusting.
