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.

Indian blast furnaces are fed with lump iron ore (10 - 40 mm) and sinter as burden. Sinter is a prepared burden, where iron ore fines of size -10 + 0.15 mm are agglomerated using mainly flux and coke. Iron ore fines of less than 0.15 mm are not utilized in sintering technology and hence are mostly discarded at mines during processing as slime.
