TECHNICAL NOTES 9 FLOTATION - Mineral Tech

Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process. In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment inside a flotation cell.

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

FLSmidth& 39;s flotation REFLUX revolution - International Mining

In traditional open top flotation cells, this mixture would simply be pulled out of the bottom of the cell. With the RFC the lamella plates come into play – which, due to the Boycott effect, allows this bubbly mixture to segregate very efficiently, preventing any loss of air bubbles to underflow. This enhanced segregation capability allows us to operate at a very high air fraction and ...

Flotation columns: Getting the most from fine ores - Outotec

This configuration may change completely depending on the ore type, particle size and product demands. Once the ore particle size is appropriate for column flotation, circuits may vary from having all cells as mechanical cells to all of them as columns, as well as various combinations of both. Figure 4 and 5 present some examples of real circuits.

A further advantage of the fluidized bed flotation cell is that it can take flotation feeds with a very high solids fraction. It is not unusual for the discharge from SAG mills to have 70% W/W solids.
