Froth Flotation Geneve
Froth Flotation Technique Method Procedure
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.
