Coal Flotation - an overview | ScienceDirect Topics
In coal flotation, only collectors and frothers are generally used as chemical reagents. The collector enhances the hydrophobic property of coal. Kerosene or No 2 fuel oil are usually used as collectors, while aliphatic alcohols such as MIBC (methyl isobutyl carbinol) and glycols are normally used as frothers.
COAL FLOTATION - Mineral Processing & Metallurgy
29-09-2003· Coal flotation is a complex process involving several phases (particles, oil droplets and air bubbles). These phases simultaneously interact with each other and with other species such as the molecules of a promoting reagent and dissolved ions in water. The physical and chemical interactions determine the outcome of the flotation process.
