  • Study of a novel environmental friendly frother in coal

    A novel environmental friendly frother FA803 was selected and compared with other three kinds of frother commonly used in coal preparation plants. It was observed that there was a relationship between the combustible material recovery with the same amount of collector and different amounts of frother and the watercarrying rate of flotation froth.
