| 摘 要： | 采用化学成份分析、XRD，SEM，EDS对LF炉精炼渣资源化特性进行检测、分析。结果表明：LF炉精炼渣中w（Al2O3）=20％-40％。主要存在两个含铝矿物相C12A7，C3A。其中：C12A7为基底相，C3A呈中心对称的条索状三维结构，易于机械单体解离，便于选矿分离利用。此外，LF炉渣中w（f-CaO）〈10％，w（C3A）=21．67％，w（C12A7）=58．67％，C12A7相中w（Al2O3）=78．86％。LF炉精炼渣活性较高，极易通过化学手段将原有结构破坏，无需煅烧，可直接进行酸碱处理提取AlO3。

| Abstract: | The properties of LF refining slag were studied with compositional analysis, XRD, SEM, EDS, etc. The results showed that LF refining slag with w（Al2O3） =20%-40%, has two main phase： C3A and C12A7. C12A7 is basis phase, and C3A phase is central symmertrical 3-D structure with clavated antenna extending in different directions. It is easy to separate mechanically and utilize after mineral processing. In addition, w（f-CaO）〈10%, while w（C3A） is about 21.67%, and w（ C12A7 ） is about 58.67% in LF refining slag, and w（Al2O3） in C12A7 is about 78.85 %. High activated LF refining slag was easily destroyed by chemical means, and Al2O3 can be extracted through acidolysis without calcineding. |
