1. Lepidolite flotation plant

01 hopper + vibrating feeder is used to automatically feed the stone into the jaw crusher.

02 Jaw Crusher is used to break big stones into small pieces and then into fine jaw crusher.

03 Fine Jaw Crusher is used to crush the output of jaw crusher to make the stone into fine sand.

04 The vibrating screen sieves more than 20mm and returns to the fine jaw crusher, and sieves 0-20mm into the silo.

Storage bin + electromagnetic feeder, automatically feeding the ball mill.

The 05 ball mill is used to grind the fine sand to 0-1mm, and cooperate with the spiral classifier to make the finished product particle size reach 0-0.074mm.

06 No. 1 slurry pump is used to transfer the overflow of the spiral classifier to the flotation machine. The flotation machine uses chemicals to obtain lepidolite concentrate.

07 The lepidolite concentrate from the flotation machine enters the concentrator, and then enters the disc vacuum filter to get the dry final product.

Crushing and screening: The lithium ore crushing and screening stage can adopt a three-stage one closed-circuit crushing and screening process, or a two-stage one closed-circuit crushing and screening process. Specifically, it is necessary to refer to the particle size of the raw ore and equip a reasonable lithium ore crushing process.

Grinding and grading: In order to ensure that lithium minerals and gangue minerals are fully free, a closed-circuit grinding and grading process can be used, using a ball mill + classifier. According to the ore characteristics of different lithium ores, some lithium ores may need to be deslimed after the grinding stage.

Beneficiation stage: Lithium ore usually has many different associated minerals. It is mainly based on flotation, often combined with gravity separation, magnetic separation and other combined processes for lithium beneficiation.

Concentrate dehydration: In order to obtain high-quality lithium concentrate, concentrate and dehydrate lithium concentrate products.
