1 Froth Flotation – Fundamental Principles

2009-8-27  Froth flotation is a good example of an engineering “system”, in that the various important parameters are highly inter-related, as shown in Figure 1. It is therefore important to take all of Chemistry Components Collectors Frothers Activators Depressants pH Equipment Components Cell Design Agitation Air Flow Cell Bank Configuration

Froth Flotation - an overview ScienceDirect Topics

Froth Flotation. Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34]. From: Advances in Colloid and Interface Science, 2005.

What is Froth Flotation? - wiseGEEK

Froth flotation has been used for more than a century in mining operations to separate valuable materials from excavated ores. More recently, froth flotation is being used for treatment of contaminated water. The process used in mining begins with the mixing of finely ground ores with water into a tank or cell. A reagent is used to enhance the ...

Principles of Froth Flotation SpringerLink

The adhesive force with which a particle clings to the air-water interface is opposed by the gravitational drag due to its mass. For successful exploitation of differences in surface properties most ore minerals must be ground finer than 48–65 mesh. A light mineral such as coal (density circa 1.4) can be floated at 10 mesh, provided the ...

Explain the froth floatation process? - askIITians

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. Ars.
