Behavior and mechanism of sodium sulfite depression of almandine from rutile in flotation system

Sodium sulfite has been utilized in the mineral industry principally as a depressant for a variety of sulfide ores. In this study, it was tested as a depressant in flotation of oxidized ore from its silicate mineral gangue. Selective flotation of rutile from almandine was investigated using sodium s...
