· The beneficiation of kyanite ores by a new dry technology is studied. Compared to the flotation method, the method reduces energy consumption from 300 – 400 to 15 – 25 kWh/ton. Dry electroseparation has made it possible to obtain concentrates with an Al2O3 content of 59 – 60% while also producing pure quartz (“tailings”).

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.

Dry methods of separation of these impurities may serve as a preconcentration step prior to wet processes of beneficiation. Dry beneficiation will eliminate the energy intensive process of dewatering small and fine coal. This paper briefly reviews the different processes and equipments used for dry beneficiation of lump, small and fine coal.

· In previous studies, it has been found that the Nigerian bentonite is deficient in terms of its fluid loss and rheological properties which includes yield point. Also, due to its high calcium content and low sodium content as opposed to foreign bentonite, it does not meet the API standard of drilling. This research was carried out to beneficiate

Bentonite is a moisture-retaining clay that swells when mixed with water. It can hold moisture for long periods and absorb moisture from surrounding soil. Bentonite can be used to backfill earth electrodes installed in boreholes or trenches to reduce resistance and increase electrode size. When mixed with water, bentonite swells to many times its dry
