Abstract
575,259. Purifying cobaltic hydroxide. MOND NICKEL CO., Ltd. Sept. 29, 1943, No. 16011. Convention date, Oct. 16, 1942. [Class 1 (iii)] [Also in Group II] In the purification of cobaltic hydroxide contaminated with nickel, iron and copper oxides, the nickel and cobalt in an aqueous suspension of the hydroxide are reduced to lower oxides, preferably with sulphur dioxide and a mineral acid such as sulphuric acid added to give a pH of 1.0 to 4.5 and obtain a solution of nickel and cobalt free from iron. In practice reduction may proceed until at least part of the iron is also reduced, acidification then dissolving all the metals. Copper and iron are then reoxidised and iron precipitated with an oxidising agent inert to nickel and cobalt, preferably the impure cobaltic hydroxide itself. The iron carries down any lead or arsenic present. The solution may be freed from copper by cementation with gas-reduced nickel powder, any iron introduced being removed by aeration. Cobalt in solution is separated from the nickel preferably by alkaline hypochlorite and may be redissolved, reprecipitated, roasted up to 2,100‹F. and leached yielding a cobaltic hydroxide free from metal impurities.
