Hematite Processing by Flotation

Hematite Processing by Flotation

Apr 19, 2016 Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores. Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with Sub-A Flotation to produce concentrates that average ...

Jul 03, 2013 Siderite, that is iron carbonate, is naturally low-grade in Fe even if the mineral content in the ore may be high. Common processing started with calcination to drive off CO 2 , followed by low-intensity magnetic separation as the FeCO 3 was more or less converted to magnetite, Fe 3 O 4 .
