Many new flotation machines are still not being used in mineral processing plants, even though the machines have significant potential to solve the current problems in the plants. For fine particle flotation, the Jameson cell and the Concorde cell are proven technologies. Hydrofloat has a good potential for coarse particle flotation.

In general you are looking at an airflow of 50 to 100 CFM per cell at a pressure of 1 to 2 (max) psig. A low pressure blower can general suffice. While some users do like having a blower for each cell, this is more common on very large cells. But even then the trend is to a common blower (often with a back up spare).

3.4. Effect of cell hydrodynamics on flotation performance. Overall recovery (R O) in a flotation cell is a function of recovery in the collection (R C) and froth (R f) phase, Eq. (4), ( Dobby, 1984 ): (4) R o = R f R c R f R c + 1 - R C. The drivers of recovery are very different in these two phases.

The first corrective reaction is to raise the pulp level or add air to the cells to quickly increase the overflow. As a band aid solution this is correct, but as the ultimate correction it is not. The purpose of the air is to provide the medium that the collector attaches and to provide a surface for the mineral to be floated away on.

Flotation Machine. Flotation machine is the also called flotation concentrator, which refers to the mechanical equipment that completes the flotation process. In the flotation machine, the ore pulp treated by adding reagents is stirred and aerated to selectively fix some of the ore particles on the bubbles. It floats to the surface of the ore ...

First off let us discuss why and how sanding occurs, because that does have an impact. Sanding can occur for many reasons, the two main and most common being; 1) poor classification ahead of flotation allowing oversized material to enter the cells, and 2) impeller wear leading to poor mixing in the cell.
