Re-beneficiation of iron ore tailings from the

Re-beneficiation of iron ore tailings from the conventional beneficiation plants The hematite ore (Fe 2 O 3) is always associated with limonite & goethite ores, which cannot be attracted by high gauss magnetic separators in the conventional beneficiation plants. Such tailings have 30-50% left-over Fe, which is a waste of natural resources.

Dry Iron Ore Beneficiation Iron Ore Separation ST

Iron ore extraction is mainly performed through open pit mining operations, resulting in significant tailings generation. The iron ore production system usually involves three stages: mining, processing and pelletizing activities. Of these, processing ensures that an adequate iron grade and chemistry is achieved prior to the pelletizing stage.

Utilization of Iron Ore Tailings as Raw Material for

The cement industry has for some time been seeking alternative raw material for the Portland cement clinker production. The aim of this research was to investigate the possibility of utilizing iron ore tailings (IOT) to replace clay as alumina-silicate raw material for the production of Portland cement clinker. For this purpose, two kinds of clinkers were prepared: one was prepared by IOT; the
