7 Factors Affecting Phosphate Froth Flotation

Generally speaking, the phosphate froth flotation index will be affected by various factors, including grinding fineness, pulp concentration, flotation time, acid type and dosage, etc. In addition, the dynamics of the flotation foam layer, inflatable volume of flotation cell, and the water quality also have effect on the phosphate froth flotation. In this article, we will elaborate on these influencing factors one by one.

Froth Flotation Process

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated well ground minerals/metals and making/playing on making them hydrophobic water-repel individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers MIBC is what allows the formation of air bubbles. Think of frother as ...

Mineral processing - Wikipedia

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles ...
