With the development of science and technology, electronic equipment and new energy industry, the demand for lithium ore has rapidly increased. Therefore, lithium ore is known as the "energy metal that promotes world progress".

Typical lithium ore is divided into 5 kinds of spodumene (containing Li2O 5.80%-8.10%), petalite (containing Li2O 2.90%-4.80%), lepidolite (containing Li2O 3.20%-6.45%), Zinnwaldite (containing Li2O 1.10%-5.00%), and lepidolite (containing Li2O 7.10%-10.10%). The more common ones are spodumene and lepidolite.

Lithium extraction plant
1. The first step is to conduct a mineral test
customers can customize the effective and scientific beneficiation process and equipment based on the ore properties and investment budget to avoid waste of resources.
2. Crushing production line

First, lithium ore goes through a crushing and grinding process in turn to produce a uniform fine particle size.
When crushing, use a jaw crusher for primary crushing, and then use a cone crusher for fine crushing.
When grinding, use a ball mill.

3. Beneficiation production line
To improve the lithium ore grade, a beneficiation process is required. Flotation is the main method for producing lithium concentrate. Other methods like magnetic separation and chemical methods play an auxiliary role.

•  Lithium ore positive flotation method

Add strong alkali (such as sodium hydroxide or sodium carbonate) for flotation after the lithium ore is ground.

After high-concentration, strong stirring, and multiple scrubbing in alkaline medium, oleic acid and its soaps are added as collectors to float lithium concentrate, leaving gangue minerals in the tank. This process does not require inhibitors.

• Lithium ore reverse flotation method

Use lime to create an alkaline environment, and add regulators like starch and dextrin to inhibit the floating of lithium ore. At the same time, use cationic collectors to make silicate gangue minerals float to the surface of the slurry, and the products in the flotation tank is lithium concentrate.

If the lithium ore contains iron minerals, a foaming agent (such as HF, resinate) can be added to further help remove impurities such as iron minerals.
Magnetic separation method
Lithium ore is often associated with complex components and the lithium concentrate obtained by flotation sometimes contains more iron. To improve lithium concentrate grade, the magnetic separation method is used as an auxiliary method.
