Flotation
How the data is used to determine flotation kinetics is a subject of a separate video. The key aspects are: the types and setup of the laboratory cell; sample to be tested, test conditions and; how the test is conducted. The standard laboratory cell and cell size for many decades has been the Denver D12 with 2.5 litre stainless steel cell.
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
