  • Flotation - Mineral Processing & Metallurgy

    The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores.

  • 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).
