| titleOfInvention | A kind of method for treating fluorine-containing waste electrolyte |
| abstract | The invention discloses a method for efficiently treating fluorine-containing waste electrolyte. Additives and reaction aids are added to the waste electrolyte, mixed uniformly and ground to less than 0.355mm, roasted, cooled at a specific rate and then crushed and washed to obtain an aluminum fluoride product , the filtrate is concentrated to further extract other by-products. The present invention reduces the primary crystal temperature of the system by adding a reaction assistant, so that the reaction is carried out in a molten state, the mass transfer efficiency is high, the reaction conversion rate is high, and the effective aluminum fluoride content in the product is high; at the same time, the holding time and cooling rate are further controlled, The aluminum fluoride grains produced by the reaction grow up, and the obtained aluminum fluoride has good fluidity, which is well compatible with the current automatic feeding equipment of industrial aluminum electrolytic cells, and realizes the green and sustainable development of the electrolytic aluminum industry. |
