Column and Contact Cell Flotation | Mining | SGS China

Flotation columns work on the same basic principle as mechanical flotation cells – mineral separation takes place in an agitated and/or aerated water mineral slurry where the surfaces of selected minerals are made hydrophobic (waterrepellent) by conditioning with selective flotation reagents.

Probably the most common, although not ideal, method of measuring level in a flotation cell is via a combination of an ultrasonic level transmitter and a target plate assembly. This technique involves connecting a 'target plate' to a float and then measuring the changes in height of the target plate using an ultrasonic instrument.

COLUMN FLOTATION MODELLING AND TECHNOLOGY

An inherent limitation with the flotation of fine partcles in conventional cells is recovery of hydrophilic (gangue) particles by mechanical entrainment in the water reporting to the froth. The method of minimizing entrainment is to create a 53Ocm thick froth at the slurry surface. The froth permits the gangue to drain back to the pulp while

Mechanical flotation Lenntech

Mechanical Flotation. In treating oily water from oil refineries, the separation of oil by mechanical flotation is called froth flotation. It is achieved by adding an organic coagulant or demulsifying agent. Flotation units are constructed with three or four cells in series. Froth flotation by injection of air may also be used for the separation of surfactants.
