Dry beneficiation of iron ore Mineral Processing
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.China understood magnetite and was happy to pay for it; Australia didn't understand magnetite, but it soon would.
