摘 要：攀钢含钛高炉渣工艺矿物学分析结果表明，钙钛矿是主要的富钛相。 采用CaO和Fe2O3对原高炉渣进行改性处理，不仅提高了钙钛矿的析出温度， 而且使另外两种主要含钛矿物攀钛透辉石和富钛透辉石析出的温度显著降低。 在适当热处理条件下， 近80%的钛组分进入钙钛矿相中，而且钙钛矿的平均晶体尺寸达90 μm， 实现了熔渣中钛组分的选择性富集并为选矿分离创造了条件。
Abstract: The analysis of processing mineralogy on Ti-bearing blast furnace slagshows that Ti component enrichs mainly in perovskite phase. The addition of CaOand Fe2O3 in the slag can increase the precipitation temperature of perovskite phase and observably decrease those of titaniumrich diopside and titanium diopside， which is in favor of the precipitation of perovskite phase. Under proper heattreatment condition， about eighty percent of titanium in the slag enrichs in perovskite phase and its average crystal size is about 90μm. This experimental result realizes the selective enrichment of Ti and the perovskite can be separated bymineral dressing method.
