Beneficiation of phosphatic ores through flotation: Review of industrial applications and potential developments

摘要: Abstract Beneficiation of phosphatic ores through flotation is the general rule for apatitic endogenic (Kola, Phalaborwa, Brazil). It also constitutes most widely used concentration process sedimentary deposits with a siliceous gangue (Florida, Senegal). On other hand, carbonate-bonded phase are not yet subject to industrial exploitation and various methods still at laboratory or pilot experimental stage. Abundant research being carried out today one several should be sooner later applied on large scale. In present day, plants make use direct (generally fatty acid collector) sometimes followed by reverse fines away in froth formed first A careful removal clays rule. The beneficiation carbonate gangue, contrary, will done penalising elements.
