Abstract
PURPOSE: To separate and remove nickel by a method wherein a solution containing dissolved nickel and ammonia is adjusted in its pH in the presence of iron ions.
CONSTITUTION: To smoothly remove nickel from a solution containing nickel and ammonia, its pH is made alkalline in the presence of iron ions to precipitate and separate nickel hydroxide. To do so, a nickel-containing solution is first added with an ammonia halide such as ammonium chloride and an ammonia salt such as ammonium sulfate. Then, as iron-nickel ion, a sulfate or a chloride, for example, is added. To prevent the formation of a complex salt, the adding is made in neutral or acidic range. Then, an alkaline liquid such as caustic soda or caustic potash is added to adjust pH to alkalinity, preferably at 13, to cause nickel hydroxide to be precipitated. At this time, an aeration treatment is effective in that it reduces consumption of alkaline solution.
