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

Column Flotation Cells
The major components of a column flotation cell are labeled. Select the component to display a description. Column cells are considered to have 2 distinct zones; the collection zone and the froth zone. Collection Zone. Because there is no mechanical agitation, column cells have no mixing zone. Instead, particles and bubbles are in …
Adjusting Pulp and Air Levels to Troubleshoot Flotation Cell Froth Movement
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.
Fine Gold Recovery by Flotation
The flotation column was developed for the improved recovery of fine particles too, and is finding commercial application. It embodies principles which are, with modification, appropriate for the flotation of gold from coarse dense sands. A small laboratory column, 1 m high by 50 mm in diameter (Figure 2), was constructed.
Jameson Cell
The cell volume of laboratory flotation equipment is much less than coal preparation plant flotation cells. As a result, the fluid dynamics differ greatly which means the dosages of the reagents (frother and collector) cannot be scaled up from the laboratory test to a pilot plant or coal preparation plant flotation cell.
Flotation of copper ore in a pneumatic flotation cell
