Mineralogical studies indicated that the +38µm material was not liberated and required milling prior to flotation. The -38µm material was well liberated and was close to the required product specification, with a Fe content of 99.7% of the target grade. The proposed beneficiation process includes de-sliming (38µm) of the SLon concentrate and milling of the +38µm material, followed by froth flotation. The new proposed flow diagram showed that the SLon concentrate of this African iron ore can successfully be upgraded.en© 2018 Taylor & Francis Group, LLC.
