laboratory. Laboratory flotation tests were carried out at various levels of grind; namely 15.33%, 19.52%, 28.16%, 39.47% and 51.51% passing 75microns sieve aperture, For each test, timed flotation concentrates were collected at intervals of 0.5, 1, 1.5 and 4 minutes. Natural pH level was maintained for all the tests.

kaolinite, illite, and pyrophyllite. Kaolinite can be removed by selective grinding followed by size classification to get an enriched coarse diaspore concentrate. The mass ratio of Al 2O 3 to SiO 2 (A/S) was used to evaluate the effect of selective grinding. The mass ratio, A/S, increased from 5.9 to 9.0 with 43% Al 2O 3 recovery. Selective ...

Copper Flotation - Mineral Processing & Metallurgy

The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation.

How Particle Size Affects Flotation

How Particle Size Affects Flotation. There is a marked particle size effect on both R and K. Table V gives an example of increasingly finer grinds in flotation with a different sulfide ore blend. Within the times of grind indicated, there is a tendency for both the over-all R and K values to increase with finer grind [see also Table III of ...

Pulp pH has a significant effect on the flotation of minerals, so the optimal pH for different collectors was first determined. The results are shown in Figure 3. With 2 × 10 –4 M NaOL as the collector, smithsonite floated well at acid pH (>70% recovery), while the recovery of quartz was at a low level (<10%).
