AI Technical Summary

Technical Problem

Existing technologies are difficult to efficiently enrich lithium in low-grade lithium clay ores, and also suffer from problems such as complex intercalation of impurity minerals, poor sorting, and high energy consumption.

Method used

A combination of dry grinding and scrubbing was used to separate lithium clay minerals and impurity minerals through two-stage dry grinding and multi-stage screening. Subsequently, scrubbing, flotation, magnetic separation and other processes were used to further separate and enrich lithium elements.

Benefits of technology

This method achieves efficient enrichment of lithium, reduces energy consumption, improves lithium recovery rate and product grade, and lowers production costs.

Abstract

The application discloses a method for enriching lithium, which comprises the following steps: S1, after dry grinding of lithium ore, fine powder with a particle size of not more than 20 mm is obtained; S2, the fine powder is scrubbed and classified to obtain scrubbed concentrate; in step S2, the particle size of the scrubbed concentrate obtained through classification is not more than 0.15 mm; and the lithium ore comprises lithium clay ore. The method for enriching lithium can realize enrichment of lithium-containing minerals and effective removal of impurity minerals, provide more high-quality raw materials for a downstream section, reduce energy consumption, and save production cost.
