| titleOfInvention | A kind of removal method of carbonate in tungsten and molybdenum waste sodium carbonate leaching solution |
| abstract | The invention relates to the field of rare metal smelting, in particular to a method for removing carbonate in carbonic acid leaching solution of tungsten and molybdenum waste, including sample preparation and detection-adding neutralizing agent to remove CO 3 2-- stirring and heating to remove CO 3 2-- testing and evaluation steps. In the method, the tungsten and molybdenum waste sodium carbonate leaching solution is sampled first, and the CO 3 2- content is detected, and then according to the detection result, a neutralizing agent is metered to remove the CO 3 2- , and then stirred and heated to further remove the CO 3 2- , and finally take samples to detect CO 3 2- to ensure that the removal of CO 3 2- reaches the standard, realize the removal of excess CO 3 2- in the leaching solution of tungsten and molybdenum waste sodium carbonate, and provide a basis for the treatment of the next link. |
