| titleOfInvention | Lithium source is utilized to put forward the method that lithium waste liquid produces sodium fluoride and the method producing sodium fluoride coproduction potassium fluosilicate |
| abstract | The invention discloses a kind of method utilizing lithium source to carry lithium waste liquid production sodium fluoride and the method for production sodium fluoride coproduction potassium fluosilicate.Produce sodium fluoride method include: lithium source is carried lithium crude product add water make slip after filter to carry lithium waste liquid；To carry lithium waste liquid or carry in lithium waste liquid concentrated solution add chelating agent react to obtain mixture；According to Na + In mixture, add HF with the ratio that mol ratio is 1:1.05～1.1 of HF and react prepared sodium fluoride slip, filter to obtain sodium fluoride product.Prepare potassium fluosilicate slip by sodium fluoride slurry filtration gained filtrate adds hexafluosilicic acid reaction, filter to obtain potassium fluosilicate product.The method of the present invention carries lithium waste liquid as raw material with lithium source, the metal ion of lithium source association is converted into the fluoride of high-quality and high added value, improves the utilization rate of lithium source associated resources, prevent the waste of resource, saved production cost；Decrease the discharge carrying lithium waste liquid, there is good economic benefit and environmental benefit. |
