Coal Flotation
Dilip Kumar, Deepak Kumar, in Sustainable Management of Coal Preparation, 2018. 5.4.2 Flotation Reagents. 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 Get Price

Searching for Effective Coal Flotation Agents by Quantum
2018 9 20 The potential of oil processing byproducts and various aliphatic and cyclic oxygen bearing compounds as coal flotation agents is investigated. In the search for highly effective coal flotation agents of specific structure and elemental composition, one useful criterion is the energy of the hydrogen bond in the intermolecular complex formed by the coal flotation agent and the Get Price

A review on flotation of coal using mixed reagent systems
Abstract The efficiency of the coal flotation process in separating fine particles is primarily influenced by the type of reagent selected. The efforts made for improved recovery of carbonaceous material with minimal ash in clean coal are endless. Today, the coal preparation industry is striving hard through several routes to improve the clean coal recovery for Get Price
