Description

Technical Field

[0001] The utility model relates to a device for extracting lepidolite from fine mud by flotation. Background Art

[0002] Lithium batteries are widely used in the electric vehicle industry due to their unique performance advantages and have become one of the main power sources for electric vehicles. Among them, lithium is mainly extracted from lepidolite ore. During the crushing and grinding processes in concentrator plants, ore over-crushing inevitably occurs, resulting in the generation of slime. Coupled with the primary slime in the ore, in order to avoid waste of lithium resources, a flotation machine is currently used to recover the lepidolite ore in the slime.

[0003] Flotation is a mineral beneficiation method that separates minerals by using the differences in the physical and chemical properties of the mineral surfaces. The foam flotation widely used in industry is characterized in that the useful minerals selectively adhere to the air bubbles in the pulp and float to the surface of the pulp, achieving the separation of the useful minerals from the gangue. During flotation, air is introduced into the pulp to form a large number of bubbles. Then, the particles of minerals that are not easily wetted by water, that is, the so-called hydrophobic mineral particles, adhere to the bubbles and float to the surface of the pulp to form a mineralized foam layer; while those particles of minerals that are easily wetted by water, that is, the so-called hydrophilic mineral particles, cannot adhere to the bubbles and remain in the pulp. By discharging the mineralized foam, the separation purpose is achieved. Existing minerals such as lithium ore need to undergo multiple flotation processes to obtain the required products. Generally, the existing flotation machines only have the function of single flotation and cannot effectively solve the problem of multiple flotation. Summary of the Utility Model
