Mineralisation and Ore Type – Karara Mining

Magnetite. Karara comprises a largescale, longlife magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (3436% Fe) than hematite ore (5864% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a highgrade (+65% Fe) concentrate for steelmaking.
