Callow Flotation Cells
Callow-Type flotation cells, with various modifications, have been employed at the Hayden concentrator since 1917. Other flotation machines, such as matless-air and mechanically agitated types, which have been tested in competition, have failed to handle tonnages or give metallurgical results equal to the modified Callow-type cells on the Ray …

1 Froth Flotation – Fundamental Principles
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.

DR Flotation Machine
In a cell-to-cell type flotation machine the sanding problem is minimised, as the pulp is mixed in every cell as it passes through the feed pipe and impeller. In a conventional open-type machine, as the pulp progresses from one cell to the next, the coarser, heavier fractions tend to stratify or settle to the bottom of the cell.

A Review of Flotation Physical Froth Flow Modifiers
Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the …

Flotation Process
The shape of a mechanical flotation tank is essentially rectangular, U-shaped, conical or cylindrical, according to the cell type and size. It is fitted with an impeller/rotor and stator/diffuser. Air enters into the device through a concentric pipe surrounding the impeller shaft either by self-aspiration or aided by a compressor.
