摘 要: 攀鋼含鈦高爐渣工藝礦物學(xué)分析結(jié)果表明，鈣鈦礦是主要的富鈦相。 采用CaO和Fe2O3對(duì)原高爐渣進(jìn)行改性處理，不僅提高了鈣鈦礦的析出溫度， 而且使另外兩種主要含鈦礦物攀鈦透輝石和富鈦透輝石析出的溫度顯著降低。 在適當(dāng)熱處理?xiàng)l件下， 近80%的鈦組分進(jìn)入鈣鈦礦相中，而且鈣鈦礦的平均晶體尺寸達(dá)90 μm， 實(shí)現(xiàn)了熔渣中鈦組分的選擇性富集并為選礦分離創(chuàng)造了條件。

Abstract:The analysis of processing mineralogy on Tibearing 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 90 [KG-*6]μm. This experimental result realizes the selective enrichment of Ti and the perovskite can be separated bymineral dressing method.
