Dry beneficiation of iron ore
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.

Bauxite Beneficiation: An Approach to Value Addition in …
The primary objective of beneficiation for non-metallurgical bauxite is to lower iron and titanium contents in the product, and also to enhance alumina values. This often requires more complicated processes, such as the use of a high-intensity wet magnetic separator, with fine grinding of bauxite to liberate the iron minerals.
