The clear liquid is evaporated into a purification liquid containing about 12~20% Li2SO4, and sodium carbonate is added to precipitate into lithium carbonate. After centrifugal dehydration, the filter slag is dried at 350℃,PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removal of iron, lithium carbonate product is obtained, the recovery rate is about 90%, and the filtrate is cooled and crystallized to recover sodium sulfate.
The production yield of LITHIUM carbonate by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC method is high, and the ore with Li2O content only 110%~115% can be treated. However, a considerable amount of sulfuric acid and soda ash become less valuable Na2SO4, and the amount of sulfuric acid should be reduced as much as possible. The advantage of this method is that the solution obtained by leaching and sintering contains 110~150 g/L lithium sulfate, and a relatively pure solution can be obtained after leaching. The sulfuric acid process can also be used to treat lepidolite and phosphorite.
PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC production of lithium carbonate as a new energy lithium battery production material, due to the rapid development of new energy, new material industry. The demand for high-end lithium products represented by battery grade lithium carbonate is strong, especially in power batteries, special engineering plastics, and other fields, which has become the main growth point of the lithium product industry.
