Figure 1: The flotation system includes many interrelated components, and changes in one area will produce compensating effects in other areas (Klimpel, 1995) Froth flotation is a good example of an engineering “system”, in that the various important parameters are highly inter-related, as shown in Figure 1.

Mineral Flotation SpringerLink

The flotation process involves crushing the ore to liberate separate grains of the various valuable minerals and gangue components, pulping the ore particles with water, and then selectively rendering hydrophobic the surface of the mineral of interest. A stream of air bubbles is then passed through the pulp; the bubbles attach to and levitate ...

Mining - Flotation Hycontrol

Mining - Flotation. One of the most widely used methods of recovering valuable minerals in the mining industry is using froth flotation tanks. Inside these tanks, the ground ore is mixed with water to form a slurry. Hydrophobic materials then separate from hydrophilic materials through the use of chemical additives.

CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION TO

Frothers, as defined by flotation operators, are compounds used specifically for creating a flotation froth. However, most collectors used in iron ore processing produce adequate froths. The general types of these frothing collectors include long-chain carboxylates, sulfonates or sulfates, and amines as listed in Table 9.1.

Background. Froth flotation is the follow-on operation, after comminution and classification, in the process of liberating and separating minerals by exploiting the differences in physical properties of the different minerals that make up an ore. Froth flotation is achieved when particles are separated based on their surface potential.
