Froth flotation - Wikipedia

Froth flotation is a process for selectively separating of 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.

Introduction to Mineral Processing or Beneficiation

The use of flotation for recovery of fine coal is also widely practiced. The flotation process begins with a modification of the surface properties of the desired mineral. The addition of surfactants renders the mineral surface hydrophobic (water-hating), so that the mineral may preferentially adhere to air bubbles and float to the surface.

Flotation is known as a separation process, based on the introduction of gas bubbles as the transport medium. Suspended particulate matter, being hydrophobic or conditioned to be so, is then attach to the bubbles and moves toward the water solution surface—i.e., contrary to the direction of gravity [1,2].Different bubble generation methods exist, belonging either to the broad class of ...

Beneficiation Process of Kaolinite Clay: Kaolin Processing

Dilution water is added to each stage of flotation to maintain dilute pulp conditions. The rougher tailings and reflotation tailings are combined and scavenged of any additional contaminant in a 4-cell "Sub-A" Flotation Machine. The tailings from this final flotation step represents the beneficiated kaolin and is pumped to a thickener.
