Optimizing Flotation Cells
Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.

Flotation Cells
A Flotation Cell must not only be able to circulate coarse material (encountered in practically every mill circuit) but also must re-circulate and retreat the difficult middling products. An alternate pulp flow …
Flotation
The flotation cell illustrated in Figure 15.3 is a mechanical cell. In the flowsheet shown in Figure 15.1, mechanical flotation cells are used for flash flotation, rougher flotation and scavenger flotation. Mechanical cells introduce air into the slurry through a rotating impeller. The impeller agitates the slurry, creates bubbles and disperses ...

Flotation Cells Design & Operating Characteristics
In its essentials, a flotation cell must provide for two main functions. First, it must supply air adequate in quantity and quality for satisfactory process kinetics. Air quantity can be defined on the basis of the narrow range provided in major U. S. commercial cells, for escape velocity, which averages near 1.2 m/min (4 ft /min).
PROCESS INSTRUMENTATION Flotation Cell
Flotation cells are often used in the minerals industry as a method for physical separation of mineral particles from the slurry by adding chemicals and pressurized air. Measurements of the level, pressurized air, chemical dosing and slurry flow are essential for process control and optimal handling of costly resources.
