  • Effect of Flotation Density on Grade and Recovery

    In an effort to test the Effect of Flotation Cell Size in Laboratory, I ended up with a test for the effect of flotation density on grade and recovery. Therefore, I here present is a Laboratory experiment that counters the reality of a full scale industrial flotation plant. By “counters the reality” I mean, larger commercial cells do not give better metallurgy than small flotation cells.

  • Calculate Flotation Cell Capacities Volume vs Retention Time

    Five minutes conditioning time and 15 minutes flotation time are desired. Adding 15% as a volume factor for aeration, the estimated flotation cell volume needed will be 290 cubic meters. If cells of 29,000 Liters volume are chosen, N will be 10. Similarly calculating for the 5-minute conditioning time at the same pulp density gives (see below).

    The effect of increasing impeller speed is to increase the air flow rate and gas holdup in the cell. Simulations with flotation kinetics showed that the gravitational force acting on the attached particles is significant. The effect is a decrease in the bubble rise velocity which in turn affects the flotation rate as predicted by the model.
