A KINETIC MODEL FOR CONVENTIONAL FLOTATION OF COAL By Frank J. Susko' and Don A. stanley2 ABSTRACT The U.S. Bureau of Mines has developed a computer model to describe a flotation process. Coal data from conventional flotation has been converted to a simple, two-parameter kinetic model developed by Reuter and van Deventer (-l,2J3.
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.
flotation is the process for fine coal beneficiation, since it depends upon the surface properties of coal . Arnold and Aplan measured contact angles of several coal samples to quantify the hydrophobicity of individual coal macerals. It was found that the order hydrophobicity of the coal macerals

Flotation is one of the most effective technologies for the up-gradation of coal fines of particle size below 0.5 mm because of the inherent hydrophobic nature of coal.Contrary to this, reverse flotation of coal in which coal particles are depressed and gangue particles floated, was developed as an alternative process to minimise the sulphur content in the coal.
Introduction to Mineral Processing. ... In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer. Sulfide and non-sulfide minerals as well as native metals are recovered by froth flotation.
