  • A Study of Fine Coal Flotation Using a Cyclic Alcohol .

    The effect of coal particle size, water quality and chemical reagents which can be manipulated in flotation plants, on the froth stability and coal flotation performance was investigated. It was found that froth stability was dependent on the coal particle size, the proportion of process water mixed with de-ionised water and the dosage of the .

  • 1 Froth Flotation – Fundamental Principles

    The Froth Recovery Package enables you to better control the froth phase, which in turn improves the performance of the flotation cell. The addition of the radial froth crowders adds a new dimension to the control strategy. It allows you to shift the grade recovery curve by allowing either deeper froth or faster froth .
