Abstract: Fine particle size cobalt metal powder is prepared by treating an aqueous solution of a soluble cobaltic ammine halide with a sufficient amount of a soluble metallic hydroxide to form a cobalt containing precipitate. The precipitate is separated from the solution and reduced in a reducing atmosphere to produce metallic cobalt.

Abstract: A process for the extraction of Ni/Co values from an ore or concentrate comprises the steps of subjecting the ore or concentrate to pressure oxidation in the presence of oxygen and an acidic solution containing halide, copper and sulphate ions to obtain a liquor containing Ni/Co values from the resultant pressure oxidation slurry. The liquor is subjected to a selective precipitation treatment to obtain a solid containing Ni/Co hydroxide. The solid is subjected to a Ni/Co leaching stage with an ammonium solution to produce a leach solution containing Ni/Co values and a residue. The Ni/Co values are separated by solvent extraction to produce solutions suitable for electrowinning of Ni and Co. The process also provides for the recovery of precious metals and other metals such as copper.

Abstract: This invention relates to a method of removing iron and manganese values and recovering cobalt values from a solution containing iron values, manganese values, cobalt values, and optionally other metal values. The method includes the step of introducing into the solution a gas mixture of sulphur dioxide and air or sulphur dioxide and oxygen so as in a single step to oxidise the iron values from the ferrous to the ferric state and to oxidise the manganese values from the manganous to the manganic state and then to precipitate the iron values as ferric oxide/hydroxide and to precipitate the manganese values as manganic oxide, leaving the cobalt values in solution.

Abstract: A monoalkyl alkylphosphonate represented by the formula (I), (wherein R1 and R2 each represents an alkyl group, with R1 containing 4 carbon atoms and R2 containing 8 carbon atoms) is used as an extractant for separating and recovering nickel and cobalt from Ni- and Co-containing scraps, waste catalysts, etc. according to solvent extraction. The use of this extractant enables one to conduct smooth pumping or the like even when cobalt is contained in a high content since the kinematic viscosity is not increased so much, and to easily obtain highly pure nickel and cobalt due to its extremely high extractive separation coefficient of nickel and cobalt.

Abstract: A process is described for leaching a value metal from an ore containing said value metal, the process including the steps of leaching the ore in the presence of hydrochloric acid so as to form a soluble metal-chloride salt in a leach solution; adding sulphuric acid to the leach solution; recovering a metal-sulphate salt from the leach solution; and regenerating hydrochloric acid. The ore may be an oxidic base metal ore, such as a zinc oxide ore; a lateritic nickel ore, such as a saprolitic or limonitic ore; a sulphide ore or a titanium ore. The value metal is typically selected from the group consisting of Zn, Cu, Ti, Al, Cr, Ni, Co, Mn, Fe, Pb, Na, K, Ca, platinum group metals and gold. The metal in the metal-sulphate salt may be the value metal, or may be a metal of less value than the value metal, such as magnesium. The regenerated hydrochloric acid is recycled within the leach process.

Abstract: Cobalt is recovered by treating aqueous solutions containing ammonia and cobalt ions with a sufficient amount of an acid in the presence of a catalyst to convert the cobalt ions to a cobalt hexammine ion which is precipitated and separated from the resulting solution. According to another aspect of the invention, a cobalt compound is precipitated from an aqueous solution of cobaltic hexammine halide by treating the solution with a metallic hydroxide and the precipitate is subsequently reduced to form fine cobalt powder.
