    The rougher and scavenger concentrates may be reground to a predetermined liberation size and then subjected to two or three stages of cleaner flotation to produce a final flotation concentrate. Cleaner flotation tailings is an intermediate product and is recycled within the flotation circuit.

  • 1 Froth Flotation – Fundamental Principles

    There is no one universal method for expressing the effectiveness of a separation, but there are several methods that are useful for examining froth flotation processes: (a) Ratio of Concentration, the weight of the feed relative to the weight of the concentrate, The Ratio of Concentration is F/C, where F is the total weight of the feed and C is the total weight of the concentrate.
