| 摘 要： | 采用光学显显微镜、图象分析和扫描电镜等多种手段，研究了樊钢镣产经选择的出处理后的改性渣中钛的赋存状态，矿物组成及结构，计算了钛在硌矿物相中的分布，测定了原料中钛矿物的解离度，为钛的综合利用提供了科学依据，研究结果表明，通过改性处理后，炉渣中大大部分钛富集于钛钛矿相中，钙钛矿晶体可以选择性析出并长大，进而采用选矿方法将其分离出来，为综合利用创造了条件，探讨了采用重选分离和浮选分离的可能性。

| Abstract: | In the blast furnace slag, titanium disseminated in various mineral phases. Titanium could be concentrated mainly in perovskite, which could be selectively precipitated and grown by optimizing the operation factors like the slag composition, temperature of heat treatment and additive agents. This study aims at establishing the titanium mineralogy and its distribution in the as-received slag and the treated slag, and the methods of perovskite separation. The chemical composition and mineralogical phases were examined by chemical analysis and polarization microscope. The microstructure and the chemical composition of the main minerals were examined by SEM, JSM-610F. |
