摘要： A process for producing a purified nickel hydroxide precipitate from a nickel-containing leach solution with impurities including one or more of the following: manganese, copper, zinc, iron and/or cobalt, so that the purified nickel hydroxide is suitable for pelletization with iron-containing ores and/or stainless steel production, includes treating the leach solution with a base to form a slurry of mixed hydroxide precipitate and low-nickel barren solution, thickening the slurry to form filter cake, washing the filter cake and contacting it with acid to dissolve nickel and other metals to produce a concentrated nickel-containing solution, subjecting the concentrated nickel-containing solution to solvent extraction with an organic acid extractant to remove metals other than nickel from the nickel-containing solution and form a solvent extraction raffinate of purified nickel solution and treating the solvent extraction raffinate with a base to precipitate the purified nickel hydroxide precipitate.
