Title Of Article :
Kyanite ore processing by carbochlorination
Latin Abstract :
Kyanite, mullite and model kyanite ore carbochlorination processing was investigated in laboratory experiments and thermodynamicsʹ calculations. The extraction of 94% alumina and silica takes place as a result of calcined kyanite carbochlorination at 1300 °C for 90 min at normal pressure. Kyanite processing into AlCl3 + SiCl4 gas mixture is proposed for high purity alumina, nanodispersed silica and solar-grade silicon production.
