Abstract

The coal wastes of Zarand coal washing Plant are accumulated in near of this plant. The rate of extractable ALUMINA from the COAL WASTE ASH is about 27%. The amount of these wastes estimated about 107tons which about 1000 tons are added to them daily. In this study ALUMINA was extracted from wastes using: Lime-soda SINTERing, LEACHING of SINTER, DESILICATION of LEACHING solution, carbonation of desilicate solution with CO2 and precipitation of Al(OH)3 calcined Al(OH)2 processes respectively. The optimum condition achieved for each process as fallows: 1-Sinteringprocess; mol ratio of CaO/SiO2 =1.8. Na2O/Al2O3=1.3 in raw materials, particle size of raw materials: 12.5 % residual of 170 mesh sieve, time=35 minutes, temperature= 1275°C, SINTER blain = 250 m2/kg. 2-Leaching process; solvent: NaOH 5.6 g/l solution, solid-liquid ratio =2, time=30 minutes and temperature=60°C 3-Desilication process; reagent: Ca(OH)2 10 g/l suspension, liquid - liquid ratio = 2, time=15 minutes, temperature: environmental temperature. 4-Carbonation process; amount of CO2 for ALUMINA precipitation in 250ml of 16.5 g/l ALUMINA solution: 1 liter/minutes for 20 minutes.5- Calcinations of AL(OH)3; temperature= 1250°C, time 30 minutes. The results showed that in optimum conditions about 74 % ALUMINA holding 99 % purification can be extracted from COAL WASTE ASH.
