3. Magnetic Separation
The magnetic separation method is usually suitable for lithium ore containing iron impurities, and the magnetic separation method is selected according to the magnetic strength of the iron material in the ore. The beneficiation mainly for iron-lithium ore can effectively improve the quality of lithium concentrate, and finally obtain higher-grade lithium concentrate.
4. Chemical Method
This method is suitable for salt lake lithium mines, from which lithium salts are extracted. The process is to evaporate the brine on the drying field, precipitate the sodium salt and potassium salt, increase the concentration of lithium chloride to about 6%, and then enter it into the factory to convert the lithium chloride into lithium products.
5. Multi-process Combined Approach
Lithium ore beneficiation technology, after years of technical iteration and innovation, the current beneficiation method is very mature, it is difficult to achieve a high beneficiation recovery rate with a single beneficiation method, so we often use a combination of multiple processes. For example, hand selection-magnetic separation process, flotation magnetic separation process, flotation, gravity separation, combined magnetic separation process, the combined process of mineral processing-chemical treatment, the combined process of beneficiation-metallurgy, etc. Each process has its own characteristics, and it can be selected according to the composition and properties of the lithium deposit and the main products.
