Lithium sulfate purification liquid production of anhydrous lithium chloride system process introduction:
The lithium sulfate purification liquid purified by the process of chelating resin calcium removal is mixed with the prepared sodium chloride solution according to a certain proportion to obtain the prepared liquid. The prepared liquid is freeze-crystallized and centrifuged to obtain a lithium chloride solution containing a small amount of sodium sulfate, and then barium chloride is added to remove sulfate to obtain a lithium chloride solution containing a small amount of sodium chloride. The solution is then evaporated and concentrated to form sodium to obtain a lithium chloride purification solution. Lithium chloride purification liquid after evaporation crystallization, centrifugal separation, drying, packaging to obtain anhydrous lithium chloride products.
The sodium sulfate decahydrate crystals obtained by freezing crystallization are re-dissolved, evaporated and crystallized to obtain anhydrous sodium sulfate product.
The above process is the sodium chloride method to produce lithium chloride, the method does not produce waste residue, the by-product sodium sulfate can be sold as a product, the process consumes more barium chloride, the cost is relatively high. Lithium sulfate production of lithium chloride can also use calcium chloride method, the process cost is relatively low, but the amount of calcium sulfate dihydrate slag is large, need to find a way to deal.
