Excess frothers give misleading results, in that too much froth is produced, gangue minerals may be floated, selectivity is poor, and recovery is misleading. In non-sulphide flotation, frothers used may be the same as for sulphides, or sodium oleate, Emulsol X-1, Ninol, or an alcohol derivative may be used.

The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In general, the minerals which …

2. INTRODUCTION Flotation is the separation of particles from a mixture by causing some particles to collect on the surface of bubbles. Floatation is an extractive process where various minerals can be selectively extracted. For example, in poly-metal ores such as Pb-Zn-Cu, floatation allows separate extraction of Pb, Cu and Zn. The process of separation of …

History. William Haynes in 1869 patented a process for separating sulfide and gangue minerals using oil and called it bulk-oil flotation.The modern froth flotation process was invented in 1901 by C.V Potter in Australia and in 1902 by G.D Delprat in Holland. In the early times, only naturally occurring chemicals such as fatty acids and oils were used as flotation reagents in a large …

Conditions of operation of froth-flotation. Froth-flotation is in general effective only on ores ground to pass 0.3-mm. aperture or less and the agitation-froth and bubble-column processes are most effectively practiced when the bulk of the feed will pass a 0.074-mm. screen.
