the older flotation technologies i.e., mechanically agitated and column cells. It should not be forgotten that in the 1930s the DenverTM flotation cell was considered revolutionary, and only in the 1950s using mechanical cells became a norm. A similar story for column cells appears from the early 1960s, however,
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
