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 project is of importance to India as while processing iron ore, particles smaller than 0.15 mm generated and are discarded as waste known as slime. Slime generated during mining is about 20-25 per cent of the total iron ore feed and it is dumped between iron-bearing mountain ranges.
