Factors affecting froth floatation Particle Size in Grinding. Both large and tiny ore particles have an impact on flotation efficiency and mineral recovery. Because of their heavy weight, flotation coarse particles are difficult to suspend in the flotation machine, and the chance of collision with the bubbles is reduced.

Barite is an important barium-containing mineral with large specific gravity (4.3-4.7) and low hardness (3-3.5).Its chemical properties are stable and insoluble in water and acid. Barite powder is mainly used in petroleum, chemical, paint, filler, and other industrial sectors. 80%-90% of them are used as mud-weighting agents in oil drilling. ...

The present paper points this out by categorizing flotation cells into mainly two subdivisions i.e., fine and coarse flotation technologies. Since the meaning of fine and coarse particle ranges might vary from one ore type to another, particularly from sulfides to industrial minerals, a general perception is considered in this work.

1. Inlaid grain size of barite The inlaid particle size of barite directly affects the particle size of its crushing, so it involves the configuration of the crusher and the vibrating screen. The general barite ore is coarse-grained inlaid, and the barite crystals are coarser and heavy. The spar ore itself is brittle and fragile, which requires the use of a …
