Coal Flotation Springerlink. Coal flotation of fine material has both economical and environmental benefits by recovering as much coal as possible from runofmine coal and by reducing air and water pollution due to the elimination of sulfur from clean coal and reduction in the solid amount which goes into the stream or in recirculating plant water.
The flotation response of two high-sulfur coals to a variety of collectors was studied in detail using a 2-liter Denver flotation cell. In comparison with dodecane as the standard oily collector, the introduction of a benzene ring into the oily collector can significantly improve its collecting ability for coal.

Joan S. Esterle, in Applied Coal Petrology, 2008 3.7.3 Froth Flotation/Column Flotation of Fine Particles. Froth flotation is a long established technique in mineral processing. Extensive discussion of flotation can be found in the book by Leja (1982); see also recent work by Fecko et al. (2005) and Melo and Laskowski (2006).
In this investigation, a comparison was done between the use of dodecane and oxidized diesel oil as collectors to float oxidized coal. FTIR was used to determine the chemical properties of oxidized diesel oil and oxidized coal, which showed that oxidized coal has less hydrophobic functional groups while oxidized diesel oil has high hydrophobic groups that will enhance oxidized coal flotation.
