Fig. 2 shows that as pH increased from 9.0 to 10.5 and then to 11.5, the pyrite recovery obtained from the flotation of the ore with 5 % pyrite decreased steadily from 94.5 to 40.6 % and then to 10.3 %. Hence, a direct link between the decreased pyrite recovery in Fig. 2 and the increased Cu grade in Fig. 1 when pH increased could be drawn. The …

A high frother concentration produces an excessive amount of froth in the flotation cell. This increases the froth overflow and flotation rate, but, unfortunately it also decreases the concentrate grade. Collector concentration has a significant effect (either linear or non-linear) on all three quantitative response variables.

Figure 1 shows the liberated bastnasite grains. Even though the data indicated a liberation size of 150 mesh, flotation tests were made on ore ground to 80 pct minus 150 mesh because a minus 150-mesh grind yielded more than 60 pct minus 325-mesh material, which was difficult to treat.

Flotation is a widely used, cost-effective separation technique for wastewater treatment [1], mineral beneficiation [2], micro-oxygenation of wine [3], fermentation [4], ink removal [5], plastic recycling [6] etc. Flotation techniques are used for the various chemical, mineral and biological industries.In this technique, components like fine particles, oil …
Interaction effects of reagents on the efficiency of copper flotation for a highly clayey low-grade sulphide ore were investigated using a central composite design. Preliminary results showed that sodium-isopropyl-xanthate (SIPX) and O-isopropyl-N-ethyl-thionocarbamate (IPETC) were found to be the most efficient collectors in the presence …
The computational basis assumes 30 percent solids in rougher flotation, 20 percent solids in cleaner, recleaner and cleaner-scavenger flotation, a ratio of concentration in rougher flotation of 3.07 an overall ratio of concentration of 5.0, and an ore specific gravity of 2.9.
