Title:
METHOD FOR PRODUCING LITHIUM CONCENTRATE AND METHOD FOR PRODUCING LITHIUM PHOSPHATE FOR USE THEREIN
Document Type and Number:
Japanese Patent JP2023129361
Kind Code:
A
Abstract:
To improve a lithium recovery rate from lithium-containing liquid.SOLUTION: Lithium-containing liquid is heated, the heated lithium-containing liquid is blended with phosphate to produce lithium phosphate, and the produced lithium phosphate is recovered. The recovered lithium phosphate is immersed in acidic liquid, producing a first lithium exudate. The first lithium exudate is then blended with a metal, forming a phosphate compound, which in turn leads to the generation of a second lithium exudate. The second lithium exudate is subjected to liquid-solid separation, separating it into the phosphate compound and the lithium concentrate. This process enables the production of lithium concentrate.SELECTED DRAWING: Figure 1
