摘　　要：从整体利用和局部利用两个方面对含钛高炉渣的综合利用现状进行了综述。指出把含钛高炉渣中的钛有效地富集到富钛相,然后分离并实现工业化生产,是高炉渣局部利用研究的重点和方向。从热力学角度分析了炉渣中钙钛矿相、攀钛透辉石、富钛透辉石、Ti(C、N)和黑钛石相作为富钛相的可行性,并对它们的结晶行为研究进展进行了总结,最后从重选和浮选两个角度分析了炉渣中钙钛矿分离的可行性。The comprehensive utilization status of Ti-bearing blast furnace slag is reviewed from the aspects of overall utilization and partial utilization.It is pointed out that the focus and direction of the research on the partial utilization of blast furnace slag is to enrich titanium effectively into titanium-rich phase,separate and industrialize the productions.The feasibility of the perovskite phase,the titanaugite,the Ti-rich diopside,the Ti(C,N)and the anosovite phase as the titanium-rich phase in the slag is analyzed from the thermodynamic,the research progress of their crystallization is summarized.Finally,the feasibility of perovskite in slag separation by gravity separation and flotation is analyzed respectively.
