flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore . Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.

Get PriceThe flotation process is suitable for stop/start operation and has a flow turndown of about 2:1 or greater depending on the design of aeration manifolds. The former is one of its advantages when dealing with a water subject to high algal loadings; a plant can be ‘switched in’ as and when needed and will give a steady quality treated water within 45 minutes ( Rees, 1979 ).
