Froth Floation | Hoffman & Lamson Solutions
Froth flotation, also called ore flotation when used in mining applications, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used methods for ore beneficiation.
Are conditioning tanks making a comeback
If you go back 40 or even 50 years you would see that most flotation circuits were built with conditioning tanks, however over the last 30 years the trend has been to remove them. I think we are now starting to see a reversal in this trend with the humble conditioning tank making a comeback. Figure 1. Conditioning tanks were traditionally …

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
