The Mechanisms Of Collector Adsorption On Salt-Type Minerals From Solutions Containing High Electrolyte Concentrations

The flotation of sylvite and also some accessory minerals is performed in brines containing very high electrolyte concentrations. Under these circumstances the mechanims of collector adsorption exhibit some characteristics which will be discussed by significant examples: - flotation separation of sylvite and halite with n-alkylammonium salts and n-alkyl sulfates - flotation separation of kieserite and anhydrite with acylamino carboxylic acids - flotation of halite by collectors which are adsorbed by hydrogen bond formation.
