Abstract

The recovery of alumina from electroslag-remelting of Ti-bearing blast furnace slag has been investigated by Bayer process, XRD methods. The effects of NaOH concentration , ratio of liquid to solid, leaching time and temperature, particle size, precipitating time and temperature, calcining temperature and time were investigated. With leaching, filtering, precipitating and calcining, alumina recovery of 75.56 pct was obtained under the conditions of NaOH concentration of 260 g/l, ratio of liquid to solid of 5:1, particle size of 85 pct passing 0.074 mm, leaching at 373 K (100°C) for 160 minutes , precipitating at 313 K (40°C) for 35 minutes and Calcining at 1473 K (1200°C) for 3 hours.
