The number of cells required for a given operation is determined from standard engineering mass balance calculations. In the design of a new plant, the characterization of each cell39;s volume and flotation efficiency is generally calculated from performing a laboratory scale flotation on the same type of equipment on the ore in question, followed by the application of empirically derived design factors.
tion of the impeller in the cell. In the forced air type machine, the impeller is located close to the cell bottom with a deeper impeller submergence, and an external air blower is used to supply air under pres II/FLOTATION/Flotation Cell Design: Application of Fundamental Principles 1503
This figure, divided by the capacity in cubic feet of any particular type of flotation cell, will give the number of such cells needed. In the case of the Southwestern Air Lift Machine it must be divided by 9.85 , which will give the length of machine required in feet.
The throughput capabilities of various cell designs will vary with the flotation machines residence time and pulp density The number of cells required for a given operation is determined from standard engineering, mass balance calculations. In the design of a new plant, the characterization of each cells volume and flotation efficiency is generally calculated from data gathered on a laboratory scale flotation using the same type of equipment for the same material mixture in question.
Froth flotation is a good example of an engineering system, in that the various important parameters are highly inter related, as shown in Figure 1. It is therefore important to take all of Chemistry Components Collectors Frothers Activators Depressants pH Equipment Components Cell Design Agitation Air Flow Cell Bank Configuration
Work Cell Realization of a Lean Process A work cells effectiveness is not separable from related elements: The product Workers must be able to manufacture and assemble the product
Flotation response = particle characteristic x cell characteristic k = P S B R F where P = a parameter related to ore floatability S B = the bubble surface area flux R F = a froth recovery factor The bubble surface area flux is defined as the total surface area of bubbles available in the cell per unit cross sectional area of cell per
