Lithium sulfate purification liquid production battery grade lithium hydroxide monohydrate system process introduction:
The lithium sulfate purification liquid purified by the process of chelating resin calcium removal is mixed with the prepared liquid alkali according to a certain proportion to obtain the prepared liquid. The prepared liquid is subjected to freezing crystallization and centrifugal separation to obtain a lithium hydroxide solution containing a small amount of sodium sulfate, and the lithium hydroxide solution is subjected to one-time evaporation crystallization to obtain a lithium hydroxide monohydrate crystal. The lithium hydroxide monohydrate obtained by primary evaporation crystallization is redissolved with pure water, and the redissolved solution is then subjected to secondary evaporation crystallization to obtain battery-grade lithium hydroxide monohydrate, and the lithium hydroxide monohydrate is then subjected to drying, screening, iron removal, crushing, mixing and packaging to obtain battery-grade lithium hydroxide monohydrate products.
The sodium sulfate decahydrate crystals obtained by freezing crystallization are re-dissolved, evaporated and crystallized to obtain anhydrous sodium sulfate product.
