The purpose of the oil in frothflotation is (1) to form, together with the water and solid of the pulp and the gas introduced into the pulp, a froth; and (2), to aid in the selection of the particles of mineral of metallic, resinous or adamantine luster in the pulp from the gangue minerals. Not all oils will perform both of these functions ...

It can be seen that for both Day 1 and Day 2 the copper grade of the concentrate sample from the FDB is lower than the copper grade of rougher cell concentrate. The column diameter of the FDB in which the froth rises was 60 mm, much more smaller than the rougher cell, and the low diameter to height ratio would restrict the lateral froth ...

This chapter explains the mathematical modeling aspects of the flotation process. More emphasis is laid on the operation of industrial mechanical cells, which play a major role in mineral separations. Graderecovery aspects of the valuable minerals, their linkage to the head grade, and the circuit dependence have been dealt with in greater depth.
