The anionic flotation of fluorite from barite using ...

2020-07-20  The flotation of mixed minerals confirmed that GS can be used as the efficient depressant in the anionic flotation of fluorite from barite. Zeta potential measurements and XPS results implied that the adsorption of GS on the fluorite surface was physisorption while hydrogen bonding might dominate the interaction between GS and barite surface. The stronger adsorption of GS on barite led to the ...

TECHNICAL NOTES 9 FLOTATION - Mineral Tech

The froth phase floats on top of the pulp phase and is formed by the bubbles that break through the surface of the pulp phase. The water in the flotation cell is conditioned to promote the formation of a more or less stable froth. The bubbles do not burst when they cross the interface and each one carries a skin of water into the froth phase.

Seven Tricks to Improve The Effect of Fluorite Flotation

When fluorite flotation uses oleic acid as the collector, it also has certain requirements on the hardness of the flotation medium (water), that is, the collection effect is better when the water is softer. As the ordinary water contains Ca2+ and Mg2+ ions, Mg2+ will seriously interfere with the separation effect of fluorite flotation. Therefore, when the water quality is hard, fluorite ...

Froth Flotation in Mineral Processing - Minerallurgy

Flotation involves three phases, solid, liquid, and froth. The solid refers to particles bearing minerals. While the liquid refers to water and the froth refers to a mixture of particles, chemical reagents, and air bubbles. A particle in water can adhere to an air bubble if its surface is hydrophobic, then it can upward to the surface with other particles that form the froth. We use
