Froth flotation | Definition of Froth flotation at ...

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible.

8.6.1 Froth Flotation. There are various methods available for cleaning fine coal, of which froth flotation has become the most common practice. Froth flotation depends on differences in surface properties between coal and shale. Air bubbles are generated within an aqueous suspension of fine raw coal with a solids concentration of less than 10%.

Abstract. 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.

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.

Coal flotation is commonly carried out with a combination of an oily collector (e.g. fuel oil) and a frother (e.g. MIBC). All coal flotation systems require the addition of a frother to generate small bubbles and to create a stable froth (Table 12.2). Typical addition rates for frothers are in the order of 0.05–0.3 kg of reagent per tonne of ...

Explaining the Process of Froth Flotation

Nov 07, 2020· 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.

Froth Flotation | Definition of Froth Flotation by Merriam ...

flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore . Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.

Jul 01, 2006· Froth residence time is possibly the most frequently used variable in the modelling of froth recovery. Two definitions of mean froth residence time, based on the air rate and concentrate slurry flow rate, respectively, can be found in the literature (Gorain et al., 1998, Lynch et al., 1981): (5) τ f = H f J g (6) τ f = (1-ε g) · V f Q s ...

2.1 Definition and analysis. In this step, the problem is defined by characterizing the feed and the design goals. Mineralogical examination, grinding tests, and laboratory-scale batch tests are conducted to identify the species to be considered in the design and the flotation kinetics of the species. A final kinetic model is not necessary ...
