Relationship between flotation operational factors and

A decrease in the stability of the froth was observed when the froth height was increased at depressant dosages of 0 and 100 g/t, and this has been attributed to an increase in the drainage of water and particles from the froth back into the pulp phase.

However, the effort to scale up flotation columns should be considerably more fruitful, for the following reasons 1. There is no mechanical agitation; 2. Close control is maintained over pulp rates and air rate; 3. Bubble size distribution is more uniform; 4. Particle entrainment into the froth is negligible; 5.

Froth Factor for Pump Sizing Mineral Processing Metallurgy

The froth factor is a measure of the air contained in the froth. It is quantified by filling a measuring cylinder or bucket, of known volume, with froth and measuring the froth column. After air dissipation the remaining water and solids volume is measured. The ratio of the original volume of froth to the remaining combined volume of water and solids is the froth factor.

Introduction to Mineral Processing Chevron Phillips Chemical

Frothers are liquids that produce the froth or foam on which the flotation process depends. The froth resembles soap suds and provides the physical separation between the mineral(s) floated and the pulp containing the waste. The froth must be strong enough to support the weight of the mineral floated and yet not be tenacious and non flowing.

Jan 25, 2013The air flow rate, impeller speed and particle size affect on the kinetics of flotation is discussed from the model results. Where the modified models are used, the results show that an increase in air flow rate will increase the flotation rate of all size fraction, but an increase in impeller speed can only increase the flotation rate of the fine and medium size.
