Aggregate size distributions in hydrophobic flocculation

Surfactants frequently used as flotation collectors are suitable for this flocculation process. The use of flotation collectors as mineral flocculants gives promising results in the inves-tigations of semi-soluble salt minerals such as scheelite (Koh et al., 1986; and Patil et al., 2001), fluorite (Sivamohan, 1988), and apatite (Wang and

froth flotation diagram of coal

In the 1st stage, coarse pyrite is removed as underflow in a conventional froth flotation operation. In the 2nd stage, the froth product from the 1st stage is subjected to froth flotation by using a coal flotation depressant and a pyrite flotation collector, thus removing most of the fine pyrite. Thus, 100 lb of coal containing ash 31.8, Get Price

Comparison of Jameson cell and jet diffuser flotation column

The flotation performance decreases by coarse or fine feeding in conventional flotation cells (Trahar, 1981). The main reason for this performance decrease is a low probability of bubble-particle collision for fine particles and unstable bubble-particle aggregate for coarse particles (Schulze, 1993; Kowalczuk et al…

Agglomeration of Particles

Agglomeration is the formation of aggregate by the sticking together of feed and/or recycle materials, and it includes the formation of agglomerate nuclei. The main objective in agglomerating fines being the conversion of ores, minerals and chemicals of undesirable fineness into agglomerates characterised by a size consistency desirable for subsequent use or processing. In metallurgical ...

PARTICLE AND BUBBLE INTERACTIONS IN FLOTATION …

Flotation separation is an important process in mineral processing and paper recycling. Flotation is a separation process used to remove particles from a liquid stream. Bubbles are introduced into the liquid stream, and, as they rise, particles may adsorb to the bubble surface. The bubbles may then carry the particles to the surface of the liquid,

Flotation is a dynamic process used for separation of hydrophobic minerals from hydrophilic ones. The size of particles is one of the most important parameters in flotation. While the flotation recovery of intermediate particles is high, the recovery of both fine and coarse particles is usually remarkably low (Trahar, 1981). Thus,

Froth flotation - Wikipedia

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.
