high recovery rate froth flotation machine flotation cell

TECHNICAL NOTES 9 FLOTATION - mineraltech.com

froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.

The rate of recovery at time t is given by the slope of the tangent to the curve at t, and the rate of recovery at time t 1 is clearly greater than the rate at time t 2. There is a direct relationship between the rate of flotation and the amount of floatable material remaining in the cell, that is:

Column Flotation • Theory and Practice

Column flotation which employs a counter-current flow of slurry and air bubbles has proved to be a better alternative to the conventional mechanical cells for separation of minerals. Because of the distinct advantages of column flotation over mechanical cells, it is gaining wider acceptance in industry.

SELECTION OF MECHANICAL FLOTATION EQUIPMENT

Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the

Effective air dispersion and distribution throughout the cell volume helps in smooth froth surface and removal.

Flotation Machine - an overview | ScienceDirect Topics

Probably the most significant area of change in mechanical flotation machine design has been the dramatic increase in machine size. This is typified by the data of Fig. 8, which shows the increase in machine (cell) volume size that has occurred with a commonly used cell manufactured by Wemco.The idea behind this approach is that as machine size increases, both plant capital …
