Basic Principles & Variables Affecting Froth Flotation

Mar 13, 2016 The purpose of the oil in froth-flotation is (1) to form, together with the water and solid of the pulp and the gas introduced into the pulp, a froth; and (2), to aid in the selection of the particles of mineral of metallic, resinous or adamantine luster in the pulp from the gangue minerals. Not all oils will perform both of these functions with all ores in all processes.

Froth floatation process is based on the principle that the metallic sulphide particles of ore are preferentially wetted by oil and the gangue particles by water. Collectors attach themselves by polar groups to grains of minerals which then become water repellent and thus, pass on into the froth. Examples are ethyl xanthate and potassium ethyl

Froth Flotation Principles

Feb 26, 2017 The Froth Flotation Machine and its operating principles are universally used for all types of flotation problems. This machine finds a wide acceptance due to its flexibility in construction, which allows the machine to be adjusted to handle pulps with divergent physical characteristics, as well as the common and intricate metallurgical problems which confront the present day operator.

Principles of Froth Flotation SpringerLink

If a particle is to be held in a mineralised froth, it must be ground to a fineness at which downward pull of gravity is insufficient to overcome its adhesion to an air-water interface. The usual commercial separation entails the lifting of a heavy metal sulphide away from a relatively light gangue by the agency of air bubbles rising through the pulp.

Write the principle behind the froth floatation process

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. The process of froth floatation starts with the Comminution process in which the surface area of the ore is increased. The ores are crushed into very fine powder sized particles and mixed with water.

What is the role of depressant in froth floatation process?

In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth. For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth.
