Studies were carried out on the recovery of valuesfrom wastesfrom magnesite mines and sponge iron plant. Rougher flotation followed by cleaning of the rougher float resulted in decreasing the silica content to below 1 % in thefinal concentrate from the magnesite mines 'waste dump' sample. The apparent porosity, bulk density and water absorption of the pelletsfired at 1750°C were 3.4-4.9%, 3.25 gm/cc and]-1-5% respectively. Results on the 'altered dunite rock'sample from the magnesite mines was also encouraging. Considering the beneficiation characteristics of coal and the associated impurities in the ESP-dust' and 'coal-char'samplesfrom sponge iron plant, a combination of magnetic separation and froth flotation was adopted for their processing. In the f nal products the ash could be brought down to -- 33 %.
