Abstract

In this paper, desilication experiments on calcined DIASPORIC BAUXITE by thermochemical treatment are investigated. For this purpose, calcined samples at specific temperature were leached with CAUSTIC SODA at 95°C. The experiments are conducted in two sections: optimizing CALCINATION conditions and determination of leaching parameters. CALCINATIONs experiments revealed that the optimum CALCINATIONs temperature and time are 1000°C and 60 minute respectively. By optimizing these parameters, 42.22% of bauxite silica content is extracted and MODULE RATIO (ratio of Al2O3 to SiO2) reaches to 2.94. According to leaching experiments the optimum leaching parameters is determined as: leaching time 120 minutes, CAUSTIC SODA concentration 200 g/L, pulp dilution 4 and particle size below 210 mm. As a result, silica extraction percentage and MODULE RATIO increase to 50.92 and 3.5 respectively.
