| titleOfInvention | A kind of method and application of resource recycling of nickel-iron alloy |
| abstract | The invention belongs to the field of nickel-iron alloy hydrometallurgy, and discloses a method and application of resource recycling of nickel-iron alloy. The method includes the following steps: (1) ball milling, pulverizing and sieving the nickel-iron alloy to obtain nickel-iron alloy powder; 2) leaching the nickel-iron alloy powder with acid solution, heating and stirring, and filtering to obtain the leachate and leach residue; (3) adding a phosphorus source to the leachate for mixing and stirring, heating, and filtering to obtain ferric phosphate and the precipitated liquid; (4) to the precipitated Add a neutralizing agent to the back liquid, heat and stir, and filter to obtain a nickel-containing solution. The present invention uses acid solution to dissolve the nickel-iron alloy, and prepares iron phosphate under the action of a phosphorus source or a phosphorus source plus an oxidizing agent, and a precipitation aid, and can further prepare a lithium iron phosphate positive electrode material as a precursor of lithium iron phosphate, and After the precipitated liquid is removed, a nickel-containing solution with low impurity content can be obtained. |
