Particle size effect on flotation process | Henan Deya Machinery Co., Ltd.

Sep 6, 20213. Process measures for fine particle flotation. Fine grains are usually mineral slimes less than 18 microns or less than 10 microns. Due to the small mass and large specific surface area of the fine-grained particles (sludge), this causes a series of special behaviors of the particles in the slurry and flotation process.

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Dense media processing cyclone

Raw coal, in slurry form, is fed to a dense media cyclone, entering tangentially into the cyclone.Three major forces act on the solid particles as they travel radially and helically inside the cyclone body, forcing the heavier particles toward the wall of the body and the lighter particles toward the center. As the lighter particles near the frustoconical portion of the cyclone body, their ...

Froth flotation - Board of Control of Michigan Tech. University

Froth flotation involves separation of particles in an aqueous pulp based on a difference in hydrophobicity. The pulp is aerated by contacting with fine air bubbles. The hydrophobic particles attach to the air bubbles and rise to and float on the surface of the pulp as a froth, leaving behind the hydrophilic particles.
