what is a differential floatation process in mining of cadmium

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) and glycols are ...
