1 Froth Flotation Fundamental Principles

1 Froth Flotation Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic by preferential wetting of mineral or ore particles by oil and gangue (impurities) by water. Collectors enhance the non-wettability of the mineral particles in the froth floatation process.

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.

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.

What is Froth Flotation?

Froth flotation is a process using air bubbles to separate materials based on their relative affinity to water. Bubbles carry reagent and hydrophobic materials to the top of a tank where they can be removed. Froth flotation has been used for more than a century in mining operations to separate valuable materials from excavated ores.

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.

This method is based on the principle that the ore particles are preferentially wetted by oil whereas gangue particles are preferentially wetted by water. This method is used for the concentration of sulphide ores. Froth flotation commences by comminution (that is, crushing and grinding), which is used to increase the surface area of the ore for subsequent processing and break the rocks into the desired mineral and gangue in a process known as liberation, which then has to be separated from ...

Flotation Froth - an overview | ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
