no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
The selection of flotation machine type is related to the factors such as raw ore properties (ore density, size, silt content, grade, floatability, etc.), equipment performance, scale of concentrator, process structure and system division. In the model selection, pay attention to the following four problems:
Flotation separation is the main method of separating lithium ore at present. All lithium ore with industrial value can be enriched by flotation, especially the fine-grained disseminated lithium ore. Flotation is done in an alkaline environment, as it not only has a good flotation result but also protects the flotation machine and is easy to ...
The kaolinite dry mining process is a simple and economical process. The ore is crushed to 25.4mm by a hammer crusher and fed into the cage mill to reduce the particle size to 6.35mm. The hot air in the cage mill reduces the moisture of the kaolin from about 20% to 10%. The crushed ore is further ground by a blown-type Raymond mill …

12.1.2 Application of Flotation Machines for Copper Mine. There are many kinds of flotation machines applied in copper mines. The KYF and JJF flotation machines are the main types of large flotation machines used in large mines, and KYF/XCF aggregate units, JJF, BF, GF, etc., are the main types used in small mines.
PIV measurement of the flow field of flotation machines. We obtain a velocity vector map of the whole flow field with a single liquid phase of KYF-0.2 flotation machine by the PIV method, as shown in Fig. 4.8a. The fluid has two kinds of flow, i.e. obviously oblique upward and oblique downward after being deflected from the stator blade.
The flotation separation process mainly includes: (1) Grind the ore finely by the ball mill or rod mill to dissociate useful minerals from gangue minerals. (2) Separate the ore by the flotation machine. Adjust the ore pulp and add flotation reagents. (3) Do the flotation processing. (4) Filter, concentrate or dry the product .
