Abstract:In order to recycle titanium fromtitanium-bearing blast furnace slag with high efficiency, a new process for comprehensive utilization of titanium-bearing blast furnace slag is explored. Sodium modification feasibility of titanium-bearing blast furnace slag is analyzed through thermodynamic calculation. According to the result of thermodynamic calculation,the feasibility of sodium modification reaction of titanium-bearing blast furnace slag is indicated under temperature of 1 423 K when the melting point of sodium carbonate is higher than 1 124 K. The empirical study on sodium modification of titanium-bearing blast furnace slag is carried out through congruent melting of phosphorous slag. According to the results,carbon can facilitate the sodium modification of titanium-bearing blast furnace slag. Along with the increase of carbon content,the sodium rate of titanium-bearing blast furnace slag increases. When the titanium-bearing blast furnace slag particle size[d0]is 0.075 mm and the carbon content reaches[nC∶][nNa2CO3=]2[∶]1, under the conditions of 1 423 K holding 2 h,the sodium rate of titanium-bearing blast furnace slag will reach 78% and maintain a stable state.
