Summary:Process for precipitating a mixed carbonate or mixed (oxy)hydroxide comprising nickel from an aqueous solution comprising a nickel salt, wherein such process is carried out in a vessel comprising (A) a vessel body, (B) one or more elements selected from draft tubes and guide vanes, (C) at least one stirrer whose pressure zone is in or between element(s) (B),and wherein the process comprises the step of simultaneously adding said solution comprising a nickel salt in or between element(s) (B) and a solution of alkali metal carbonate or hydroxide in or between or outside element(s) (B). Procédé de précipitation d'un carbonate mixte ou d'un (oxy)hydroxyde mixte comprenant du nickel à partir d'une solution aqueuse comprenant un sel de nickel, un tel procédé étant mis en ?uvre dans un récipient comprenant (A) un corps de récipient, (B) un ou plusieurs éléments choisis parmi des tubes d'aspiration et des aubes de guidage, (C) au moins un agitateur dont la zone de pression est située dans ou entre l'élément(s) (B), et comprenant l'étape consistant à ajouter simultanément la solution comprenant un sel de nickel dans ou entre l'élément(s) (B) et une solution de carbonate ou d'hydroxyde de métal alcalin dans ou entre l'élément extérieur(s) (B).
