Energy transition to promote lithium battery has become a hot topic, lithium resource acquisition to mineral lithium extraction. Lithium ore processing involves crushing, screening, grinding and flotation, etc. Vertical mills are suitable for processing medium and high hardness ores. Shibang Group provides efficient solutions to help lithium resources to be utilised efficiently and promote energy transformation.

From coal and oil to power batteries, energy transformation is profoundly changing production and life. With the rapid development of the new energy vehicle industry, lithium battery has become a hot topic of discussion, known as the "oil of the new era".

Lithium is a highly active element, usually in the form of compounds in the earth's crust, mainly distributed in the form of salt lake brine, hard rock lithium ore and lithium clay ore. Due to the limitation of production cost and process maturity, mineral lithium extraction has become one of the main ways to obtain lithium resources.

Lithium ore resources and its processing flow

Lithium ores are usually associated ores with low grades, and precious lithium resources often coexist with other substances. In order to separate out the single lithium resources, lithium ores such as lithium pyroxene and lithium mica need to go through a series of professional processing steps, including crushing and screening, milling and grading, flotation and purification, and tailings magnetic separation. Crushing, screening and grinding of lithium ore are at the front end of the whole process.

Preliminary crushing and screening

The lithium ore mined from the mine is usually large in size and needs to be initially crushed by a jaw crusher. The coarse material is then sent to the medium crushing cone crusher for further crushing, and the output material enters the vibrating screen for pre-screening. The qualified material enters the fine crushing cone crusher, and the unqualified material returns to continue crushing. Eventually, the output fines below 15mm enter the next step of grinding.

Grinding and Flotation

The hardness of calcined lithium ore is high, and it is difficult to grind it, so it is recommended to use vertical mill. This equipment integrates crushing, drying, grinding, classifying and conveying, and is capable of handling medium and high hardness ores, with a single machine capacity of 6-80 tonnes per hour. The fineness of the finished lithium ore generally needs to be ground to 200 mesh to get better flotation effect and ensure the uniformity of mixing in the downstream production process. The powder selector of the vertical mill adopts cage powder selector and conical rotor powder selector, which has high powder selecting precision and stable quality of finished products, and is able to meet the requirements of new energy field for high-precision processing of lithium ore.

Innovation of technology and equipment

In the process of lithium ore processing, advanced equipment and technology is the key. As an industry leader, Worldbest Group provides a variety of efficient ore crushing and grinding solutions. For example, Worldbond's hydraulic cone crusher not only improves production efficiency, but also significantly reduces energy consumption and maintenance costs, providing strong support for the efficient utilisation of lithium ore resources.

Conclusion

With the continuous progress of new energy technology, the efficient use of lithium resources has become the focus of the industry. Through continuous optimisation of lithium ore processing technology and equipment, it will be able to better meet the demand for lithium resources in new energy vehicles and other fields, and promote the energy transition to a new level.
