    Coal is commonly carried out with a combination of an oily collector e.g. fuel oil and a frother e.g. MIBC. All coal 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 per tonne of coal feed.
