A New Technology for Preparing Rich-Titanium Material by Hydrometallurgy

Abstract:

This paper studies on a new technology for preparing rich-titanium material with titanic slag of electric furnace by hydrometallurgy. Under the condition of temperature 120°C, pressure 0.2MPa, 2h duration holding pressure, NaOH concentration 60～100 g/L, high pressure alkaline leaching can destroy the sosloid structure and selectively remove SiO₂ and Al₂O₃ in the Electro-titanium slag, Then rich titanium product of TiO₂＞90% was prepared from electro-titanium slag of TiO₂80~87%by using acid leaching and washing, on the condition that temperature>80°C, time 2h, acid concentration 25g/L.
