Notes on Method of Froth Floatation

Switch flotation method – Gunge sticks to the air pocket, and metal particles tumble to the base. This is the way it works. How froth floatation works. Some of the minerals in the ore are picked up by a liquid film and floated on top of a mass of fluid pulp. This process, called floatation, separates the valuable minerals from less valuable ones.

Fundamentals of froth flotation

Froth flotation is a physicochemical process that is used to separate fine mineral particles from aqueous suspensions by selective attachment of some types of minerals to air bubbles.

Basic Principles & Variables Affecting Froth Flotation

If, on the other hand, flotation is to be attempted with but little agitation intervening following the introduction of the oil, a mobile and relatively soluble oil must be used. The quantity of oil necessary in any froth-flotation operation depends upon: the kind of oil used; the recoverable mineral content of the ore;

Editorial for Special Issue "Design, Modeling, Optimization

Among the influencing factors shown in Fig. 1, particle size is the most important [[9], [10], [11]].Froth flotation works best when minerals are in an intermediate particle size range, typically from 20 to 150 μm, but varies with the types of minerals [[10], [11], [12]].When particles are smaller than about 20 μm, value mineral recovery and separation selectivity drop quickly.
