Beneficiation process has been developed to provide selective separation of silica dust material. This material is produced from the furnaces of silicon metal and ferrosilicon and considered to be of little or even of no value material. Cyclone classification of original sample, 90% – 15 μm in size, followed by froth flotation using cheap local collectors was carried out to remove the unburned and the iron contaminants. Dewatering tests were also carried out for the diluted pulp concentrate. A simple flowsheet has been suggested to produce bright silica fine product exceeded 99.5% SiO₂, from starting material with 95.5%.
