sulphide flotation recovery froth floation

Thefroth flotationprocess mainly includes grinding, slurry adding,froth flotationseparation and dehydration of foam products and tailing products afterfroth flotation. Before theflotationoperation, the ore needs to be ground to an optional size range by the grinding mill, generally less than 0.1 mm.

Sulphide Flotation an overview ScienceDirect Topics

Insulfide flotation,recoveryand selectivity are fundamentally dependent on the relative rate constants of various mineral phases (Boulton et al., 2003). Therefore, an evaluation of the hydrophobicity balance by mineral particles requires accurate selection of the mineral phase.

Sulphideores are concentrated byfroth flotationprocess.

The single most important operation used for therecoveryand upgrading ofsulphideore. Onlysulphideores are concentrated byfroth flotationprocess because pine oil selectively wets thesulphideore and hence brings it to thefroth. Thesulphideores preferably wetted by the oil and the gangue with the water. Hence A is answer.
