Title:
METHOD FOR LITHIUM ENRICHMENT
Document Type and Number:
WIPO Patent Application WO/2024/051102
Kind Code:
A1
Abstract:
A method for lithium enrichment, comprising the following steps: S1, performing dry grinding on lithium ores to acquire fine powder having a particle size not larger than 20 mm; and S2, scrubbing the fine powder and then performing classification to obtain a scrubbed concentrate. In step S2, the particle size of the scrubbed concentrate obtained by classification is not larger than 0.15 mm; the lithium ores comprise lithium clay ores. The method for lithium enrichment can achieve enrichment of lithium-containing ores and effective discarding of impurity ores, thus providing high-quality raw materials for downstream working sections, reducing energy consumption, and saving the production cost.
