Precise Air Flow Measurement Improves Efficiency of Mining

Flotation cells require the precise control of compressed air because the frothing process efficiency is based on the speed of the froth as it moves from the surface of the slurry to the recovery area The speed of the froth is controlled by the air bubbles induced into the flotation cell tank level and reagent dosages Get price

(S 1)

tankage is twice as high for DAF flotation systems compared to Froth Flotation systems As a result tankage is much larger in DAF systems than Froth technology systems 5 The operating cost of Froth Flotation Systems is significantly higher than DAF systems because of the chemistry cost for the surfactant in Froth systems Get price

OPTIMIZATION OF AIR

A mayor constraint on column flotation capacity is froth overloading The carrying capacity of the froth depends on the bubble surface area available for bubble-particle attachment The bubble surface area and hence carrying capacity can be increased by reducing the average size of Get price
