Waste Reduction at the Source and Waste Recycle through Briquetting of the Reduction Charge in the black- ash process

Physical losses of material as flue dust in the oil fired rotary furnaces of black ash process for barite reduction have been arrested using briquetted charge. Similarly fine particles of barium sulphate obtained in the purification of barite could be recycled as a resource by exploiting advantages of catalysis and briquetting techniques.
