flotation concentration iron ore

CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION TO ...

The flotation method of concentration, used extensively for other metal ores, has only recently been utilized for hematite iron ores. It can be applied as either the sole concentration process or as a final concentration stage to ensure a high-grade product. In the flotation process, air is bubbled through a suspension of fine iron ore in water

Two-step flotation recovery of iron concentrate from ...

Aug 05, 2010  The flotation of pure and natural carbonaceous iron ore samples in the oleate flotation system was investigated. Starch can depress hematite effectively in a wide pH range, but cannot depress siderite efficiently in neutral conditions. The flotation recovery of pure hematite, siderite, and quartz in the oleate-starch-CaCl2 system is significantly different when the slurry pH varies from 4 to 12.
