| titleOfInvention | Method for treating nickel deposition solution |
| abstract | The invention discloses a method for treating a nickel precipitation solution, which comprises the following steps: (1) mixing the nickel precipitation solution with lime cream for precipitation so as to obtain a liquid-solid mixture; (2) carrying out thickening treatment on the liquid-solid mixture so as to obtain overflow containing nickel hydroxide precipitate and underflow containing calcium sulfate; (3) the overflow of the nickel hydroxide containing precipitate is filtered to obtain nickel hydroxide and a filtrate. The method adopts lime milk as a precipitator, simplifies the prior nickel precipitation process, saves the production cost of not less than 2000 yuan per ton of nickel compared with the prior nickel precipitation technology, simultaneously enables the direct recovery rate of nickel to reach 96 percent, has obvious effect, can treat the nickel at large flow, and is suitable for industrial production application. |
