The unutilized iron ore fines (IOF, − 10 mm, 45% to < 60% Fe(T)) left at various mine sites during blasting and processing are rich in goethetic-hematite associated with high clay and considered a potential iron ore resource. The variation of loss on ignition (LOI) from mines to mines is based on the goethite and clay mineral content. The clay …

The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with 63.5 % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from 26.5 Mta capacity to 28 Mta in the forthcoming years.

This route proposes to beneficiate the feed iron ore fines partially after properly studying the fractional analysis. Amount of tails generated is considerably lower than that of the full beneficiation mode with almost similar slurry concentrate characteristics. This eliminates the need to have a full-fledged tailing pond to some extent.
