Column Flotation | FL
When it comes to froth flotation and recovery, there is no one-size-fits-all solution; instead, mining sites find that the best route is to combine multiple pieces of froth recovery equipment, to create a hybrid circuit solution capable of ensuring the best possible recovery rates. Column Flotation Cells are an integral part of that circuit.

The Recent advances in FL Inc. as a pioneer company in flotation processes can be classified into three groups: i) forced-air flotation machines (Dorr-Oliver) designed for recovering fine particles in terms of imposing high energy to these particles, concerning their low inertia in rupturing the water film; ii) induced-air flotation cells ...
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
