Advantages and Disadvantage of Froth Flotation

Froth flotation method is a kind of mineral processing technology that the solid minerals emerge from water suspension (slurry) according to the physical and chemical properties of the mineral surface.. According to statistics, more than 60% ~ 70% ore in the world is separated by froth flotation method, involving more than one hundred kinds of minerals.

Flotation Froth - an overview ScienceDirect Topics

Froth flotation is influenced by several operating factors. The most important of these is pH. Interaction with collector and formation of hydrophobic film at a mineral occurs within certain pH range. In the case of sulfide minerals, at pH above a certain value, called critical pH, the collector uptake does not occur and the mineral ceases to float. This critical pH varies for different ...

Principles of Froth Flotation SpringerLink

To achieve selective flotation of mineral particles, whether by their removal in a froth or by the less-used method of agglomeration, specific characteristics of one or more of the mineral species present must be adequately developed. Provided these produce sufficiently marked differences of behaviour in the presence of air, they can then be exploited. If a particle is to be held in a ...

5 Types of Phosphate Froth Flotation Process

The direct froth flotation process is to grind the phosphate ore until the minerals among the ore are dissociated after one stage grinding, suppress the gangue minerals by adding inhibitors, and then add the collector to enrich the phosphate minerals in the foam. This process must be combined with strong inhibitors to obtain best effect.

Mineral particles report to the froth flotation product either because of the selective attachment of hydrophobic particles or water entrainment of non-selective hydrophilic particles [13,16].

As such, entrainment greatly deteriorates the selectivity of the froth flotation process

Froth flotation is a three-phase separation process in which a target mineral in an aqueous suspension is first rendered hydrophobic using “collectors”. When air is dispersed into the suspension, the hydrophobic particles selectively attach to air bubbles and the bubble-particle aggregates float to the surface and recovered in a resultant “froth” or “concentrate” layer. Remaining mineral impurities called “tail” are

In flotation cells, we add air, create bubbles of a certain size and speed that provide the surface area to do the flotation. The more bubbles and the smaller the bubble, the more surface area we have to do the work. This surface area we create is known as the surface bubble flux (Sb) and controls the kinetics of flotation
