| titleOfInvention | A method for green cleaning and defluorination of fluorine-containing mixed rare earth chloride solution |
| abstract | The invention discloses a method for green cleaning and defluorination of a fluorine-containing mixed rare earth chloride solution, which has the characteristics of including the following steps: Step 1, adding a certain amount of carbonic acid to a fluorine-containing mixed rare earth chloride solution with a predetermined rare earth concentration rare earth, and then carry out a defluorination reaction at a predetermined reaction temperature, a predetermined reaction time, and an initial pH condition; step 2, after the defluorination reaction is completed, filter to obtain a filtrate and a filter residue, and the filtrate is a low-fluorine mixed rare earth chloride solution after defluorination, and the filter residue It is a rare earth compound mainly composed of rare earth fluorocarbonate, and the filter residue is returned to the process of preparing a fluorine-containing mixed rare earth chloride solution in step 1, so as to realize the recovery of rare earth and fluorine resources. The method realizes defluorination, and at the same time, the added rare earth carbonate is all converted into rare earth products, the cost of defluorination is low, and the overall process does not generate secondary defluorination waste residue, which belongs to a green cleaning process. |
