Contact Cell Flotation. The flotation contact cell is a slurry aeration device with no moving parts. The contact cell consists of two main components: The contactor is a chamber in which feed slurry and flotation air are brought together under pressure. Pressure is maintained by a restriction located at the downstream end of the contactor.

Separating minerals in a froth floatation cell is a particularly corrosive, difficult-to-maintain operation. While the mixture of slurry, surfactant, water, air and froth in a given process varies, the ultimate effect on the slowly rotating rake and its related components is too often the same: failed seals and bearings, plus unplanned downtime and lost productivity.

Selection of the best control valve for flotation column and cell control. Release date . Froth depth in a flotation cell is an excellent indicator of flotation cell performance. The thicker the froth the more concentrate is entrained within. There are several factors which influence control such as air addition rate, flocculant ...
Efficient flotation for all applications and wide particle size range. There are many factors that can affect your flotation process. The two aspects that have the strongest impact on a flotation circuit’s efficiency and performance are metallurgical recovery and flotation cell availability.
Flotation Developments & Best Practice. ... The key factors for sizing and equipment selection are the ore character based on flotation test work and plant experience.” The retention time required at each stage is also a key factor he discussed. “The change from square Hough trough cells to cylindrical tank cells up to 600 m3 in size has ...
Flotation cells require precise control of compressed air because the frothing process efficiency is based on the speed of the froth as it moves from the surface of the slurry to the recovery area. The speed of the froth is controlled by the air bubbles induced into the flotation cell, tank level and reagent dosages.
:: Selecting Flotation Cells: How Many and What Size? Lower ore grades have driven the industry to larger throughputs and thus larger equipment over the last 20 years. Flotation cell sizes of up to 200m 3 are now available with 150m 3 cell installations being common.

The metallurgist flotation mainly made up of slurry-supporting Trough, mixing device, aeration device, mineralized bubble discharging device and motor. Flotation cell is mainly used to select nonferrous metals such as copper, zinc, lead, nickel, gold, etc., and also be used for coarse selection and selection of black metal and nonmetal.
Example 2 - Phosphate Flotation A project in which an entire concentrator was converted from mechanical flotation cells to column flotation cells over a period of 2 years as part of a program to reduce plant operating costs. For complete details, download the paper below Industrial Applications of Column Cells as Roughers
For flotation of crude concentrates flotation machines IF-20RC and IF-30RC were designed. The characteristic feature of the machines is vertical pulp flow thro-ugh the flotation cell. Those machines have to be used as single flotation cells. When there is a need to use multiple flotation cells it is recommended to use them

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
