Combined regulation of oxidized pyrite flotation by sodium sulfide and malic acid: Experimental investigation and DFT calculations

Surface oxidation of pyrite (FeS 2 ) during flotation produces hydrophilic Fe(III)-bearing species, substantially decreasing its floatability. In this study, a combined sodium sulfide (Na 2 S)-malic acid regulation system was developed to improve the flotation response of oxidize...
