Flotation Process - an overview | ScienceDirect Topics

The flotation process depends on several design and operational variables. We consider a superstructure that includes the following three flotation stages: the rougher, which processes the feed; the cleaner, which generates the final concentrate; and the scavenger, which generates the final tailing, as shown in Fig. (1). This is a simple ...

Graphite ore flotation processing flow chart

The flotation method is a relatively common method for purifying minerals. Since the graphite surface is not easily wetted by water, it has good floatability and is easily separated from impurity minerals. The flotation of graphite ore is generally carried out by positive flotation followed by reverse flotation of the flotation concentrate.

Froth Flotation Process - Mineral Processing & Metallurgy

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.
