depressants and dispersants in mineral flotation the challenge is to maximize the recovery of desired minerals while rejecting unwanted gangue components. depressants are required to give a low affinity to active sites on valuable mineral surfaces and a high affinity for gangue minerals and some sulfides.

froth flotation (sulphide & oxide)

the flotation of cerussite is best performed following sufficient preconditioning to precipitate dissolved lead as lead sulphide and to sulphidize the mineral surface prior to collector addition. however over sulphidizedcerussite will significantly reduce flotation response. dosage levels of nahs for galena flotation are significantly lower.
