Heavy Media Separation an overview ScienceDirect Topics

This method involves preheating of the ore to about 400–500 °C, followed by electrostatic separation. Preheat temperature depends on the amount of the clay in the feed. If the slime associated with the ore is present, then preheating temperature increases. In these studies, the optimum preheat temperature is between 200 and 350 °C.

Froth flotation

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and

For instance, an excessive use of activators can induce coagulation of the clay particles and makes the separation difficult. Further, activators may also cause the flotation of the clay particles themselves rather than the colored impurities, resulting in a poor separation efficiency and a loss of clay recovery.

Liquid separation procedures can generally be assigned to one of two groups. (i) Gravity separation techniques: use a gravity difference between particles within a residue.
