MINERAL PROCESSING. FROTH FLOTATION. Froth Flotation was initially developed to separate sulfide minerals such as chalcopyrite from gangue. Collectors and frothers are added to a slurry to attach selected minerals to air bubbles to float them to the surface to be collected as a concentrate. Many sulfide and oxide minerals can be floated.
One of the functions of minerals processing, is concentration. Concentration may be simply de ned as the upgrading of a mineral. That is, to increase the fraction of the valuable material versus the discard material. This may be achieved with a host of di erent processes. What

228 Wills' Mineral Processing Technology and since the particle and the displaced fluid are of equal volume, dx/dt - ( Ds - Df Ds ) g _(1-De D~ ) g (10.3) where D s and Df are the respective specific gravi- ties of the solid and the fluid. The initial acceleration of the mineral grains is
Mineral processing also called : 1-ore dressing 2-mineral dressing, 3- milling. In case of mineral processing one of the main aim is to regulating the size of the ore. We can define mineral processing as a process of physically separating the grains of valuable mineral from the gangue mineral, to produce an enriched portion or
The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite.
Spiral concentrators are a gravity based concentrating device, that separates light density granular and sandy (18 mesh to 200 mesh (1 mm to 0.075 microns)) consistency material from heavier density material. In order to have a good separation, there should be a difference in SG's of at least 1.0.
