to get a recovery of 85.7% TCu can be computed as follows: t = 1.113t + 0.303 0.857 t = 0.954t + 0.260 0.046t = 0.260 t = 5.65 minutes However, 85.7% TCu is the recovery obtained after 6 minutes of sulphide flotation. The actual recovery calculated from the equation by putting in 6 minutes of flotation time is 85.9%.
Time-recovery plots were fit using the modified first order rate equation for flotation kinetics, namely, 12, = ev"), and flotation rate constant and the cumulative recovery at time infinite (R,) were computed.
Published studies an flotation kinetics have been summarized recently by Gaudin.l When comparing flotation rates, it is more satisfactory to compare straight line relationships between recovery and flotation time than exponential curves resulting from plotting cumulative recovery vs cumulative flotation time.

Since the cumulative grade of silica in the concentrate increased with flotation time all through (Fig. 8 b), this recovery pattern characterizes entrainment [21, 22]. Since water recovery suffices to sustain entrainment, entrained matter forms the larger fraction of the mass pull after hydrophobic flotation response has subsided, explaining increasing …

In some (Cu-Mo) mines around the world, Mo recovery is low due to poor liberation, fine dissemination in gangue minerals, and losses of Cu and Mo to tailing streams. Studies to recover these materials as a new resource will increasingly become an attractive option.

Since the cumulative recovery of a component in the concentrate is proportional to flotation time, the flotation process can be considered as a time-rate recovery process. Therefore, a mathematical flotation model that incorporates both the recovery and rate function can completely describe flotation time-recovery profiles.

The test is a means of determining the flotation characteristics of an ore. It is conducted in a laboratory scale cell usually with a volume of two point five litres. The intention is to generate relationships of cumulative recovery, mass pull and grade versus time and use these to evaluate the floatability of metal, mineral and gang.
