摘要： Provided are an impurity-element removing method for selectively removing magnesium from a nickel-containing solution, and a method for producing high-purity nickel sulfate using the impurity-element removing method. The production method includes a production process in the production method of producing high-purity nickel sulfate from a nickel-containing solution, and the nickel-containing solution in the production process is subjected to an impurity-element removal treatment that includes: a hydroxylation step of adding an alkali hydroxide to the nickel-containing solution in the production process to form a hydroxylated slurry; a carbonation step of adding an alkali carbonate to the hydroxylated slurry to form a carbonated slurry, and recovering nickel component from the solution; a solid-liquid separation step for the slurry thus obtained; and a neutralization step of subjecting a solution after reaction obtained by solid-liquid separation to a neutralization, and recovering an impurity element included in the nickel-containing solution in the production process.

摘要： The recovery of cobalt and/or nickel from solvent extraction strip solutions containing copper and zinc is effected by sequentially precipitating copper and then zinc (as contaminant metals) from the strip solution by individual sulfide sparges. After these metals are removed, the cobalt or nickel values are precipitated from the solution by the addition of carbonate ions.

摘要： Nickel-metal-containing solids comprising for use in manufacturing nickel metal complexes are disclosed. The nickel-metal-containing solids are made by reducing basic nickel carbonates. By varying the molar ratios of carbonates and bicarbonates to nickel salts, the methods provide basic nickel carbonates that produce superior nickel metal-containing solids that react more effectively with phosphorous-containing ligands. The phosphorous containing ligands can be both monodentate and bidentate phosphorous-containing ligands.
