Savona Equipment is a flotation cell supplier worldwide. Froth flotation is a process for selectively separating hydrophobic materials from hydrophobic. This is used in several processing industries. Historically this was first used in the mining industry. Froth flotation improved the recovery of valuable minerals, such as copper- and lead-bearing minerals.
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.
