Canadian Patent Application No.:  CA  2379491 Abstracts A method of effecting intimate mixing and reaction of a metal in particulate form with a reactant gas to form a gaseous product, said method comprising passing a feed stream of said reactant gas through an elongate conduit into a reaction  chamber at such a flow rate as to effect drawing of said particulate metal through said elongate conduit in intimate admixture with said gas from a … Continue reading →

Canadian Patent Application No.:  CA  2585541 Abstracts An improved method of reducing a mixed metal oxide composition comprising oxides of nickel, cobalt, copper and iron in a hydrogen atmosphere to produce a mixture of the  respective metals, the improvement wherein the atmosphere further comprises water vapour at a concentration, temperature and time to effect selective reduction of the oxides of nickel cobalt and copper relative to the iron oxide to produce the metallic mixture … Continue reading →

Canadian Patent Application No.:  CA  2206217 Abstracts A closed loop, carbon monoxide self-contained continuous process for the production of nickel or nickel coated objects by the nickel vapour deposition process, comprising placing an object to be treated with nickel carbonyl by said nickel vapour deposition process in a deposition chamber; feeding a gaseous mixture of nickel carbonyl and carbon monoxide to said deposition chamber; depositing nickel on said object to produce said nickel or … Continue reading →

Canadian Patent Application No.:  CA  2525625 Abstracts A process for the production of pure metallic nickel and cobalt from metallic ores comprising oxides of nickel, cobalt and iron, the process comprising (a) treating the ores with hydrogen at a pressure of at least atmospheric pressure and an effective temperature, in the presence of chloride anion or an in situ generator thereof precursor; to produce a first mixture comprising particulate nickel and particulate cobalt; (b) … Continue reading →

Canadian Patent Application No.:  CA  2525466 Abstracts A process and apparatus for the production of a deposited metallic nickel product from an inactivated, pre-activated metallic nickel source, the process including treating the nickel source with hydrogen at a nickel activation temperature selected from 150-350°C, preferably, 150°C to effect re-activation of the nickel source; treating the re-activated nickel with carbonylation carbon monoxide to produce a gaseous mixture containing nickel carbonyl and carbon monoxide; collecting the … Continue reading →
