Flotation Reagent - an overview | ScienceDirect Topics

Coal flotation is commonly carried out with a combination of an oily collector (e.g. fuel oil) and a frother (e.g. MIBC). All coal flotation systems require the addition of a frother to generate small bubbles and to create a stable froth (Table 12.2).Typical addition rates for frothers are in the order of 0.05–0.3 kg of reagent per tonne of coal feed.
