The crystal surface of lithium carbonate made from spodumene is glassy and the fracture is fatty. Hardness 5 ~ 6, density 2. 6 ~ 2. 67g/ cm3, mineral resources are not much. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic Before iron, during roasting, in addition to alkali metal can react with sulfuric acid to produce soluble corresponding sulfate, other iron, aluminum, calcium, magnesium, etc., also react with sulfuric acid to produce corresponding sulfate.
In the leaching process, although some impurities in the clinker can be removed, the remaining impurities remain in the leaching solution, and need to continue to purify and remove to ensure the quality of the product. The leaching solution was purified by alkaline calcium removal method, and the pH value was increased to 11 ~ 12 by alkaline agent lime milk (containing CaO100 ~ 150g/L), and the magnesium and iron were hydrolyzed into hydroxide precipitation, and the iron removal was carried out by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC.
Then sodium carbonate solution (containing Na2CO3 300g/L) is reacted with calcium sulfate to produce calcium carbonate precipitation, thereby removing calcium in the leaching solution and calcium brought in by the alkalizing agent lime milk. The alkaline calcium removal slurry is separated by liquid-solid, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic iron removal, the resulting solution is the purification liquid, the calcium-lithium ratio is less than 9.6×10-4, the filter cake is the calcium slag, return to the slurry leaching.
