coal flotation process

Aug 06 2010 · Coal flotation is commonly carried out with a combination of an oily collector eg fuel oil and a frother eg MIBC All coal flotation systems require the addition of a frother to generate small bubbles and to create a stable froth Table 122 Typical addition rates for frothers are in the order of 005–03 kg of reagent per tonne of coal feed
