The gravity concentration allows obtaining of iron concentrate from the well-prepared feed (size fraction -53+20 micron) but with very low recovery. Thus, the hematite concentrates with weak silica content and satisfactory iron recovery were obtained by reverse cationic flotation, when it was fed with iron pre-concentrate produced by high gradient

However, below the OAI, magnetic minerals constitute a much larger fraction of the total dissolved Fe(II) ranging from 13.6 to 32.2 per cent depending on magnetic mineralogy. Most of this iron is possibly in the form of nanophase magnetic particles, possibly associated with biologically induced mineralization processes occurring below the OAI.

The invention discloses a fluidization roasting separation method of siderite-containing mixed iron ores. The fluidization roasting separation method comprises the following steps: carrying out multi-stage fluidization preheating on the siderite-containing mixed iron ores with the particle size of -0.5mm in an oxidizing atmosphere until the temperature of the mixed iron ores is 600-800 DEG C ...
