1 Froth Flotation – Fundamental Principles - MAFIADOC.COM

As the rate of coal flotation increases, the rate of gangue flotation increases proportionately. This is typical of a froth entrainment process acting on the gangue. 1.5.2.2 Synthetic and Natural Frothers The original frothers were natural products, such as pine oil and cresylic acid.
