摘要: 鄂西赤铁矿矿石储量大,属于高磷微细粒嵌布的难选鲕状矿,其尾矿产生量大、粒度细、铁含量高且回收难度很大,硅铝含量偏低,直接堆放将会对环境造成污染,必须加以综合利用。在对鄂西高磷赤铁矿尾矿基本特性综合分析的基础上,采用压制成型法,进行了用其制备烧结砖的试验研究。结果表明,在成型水分12%~15%、成型压力20~25 MPa,烧结温度950~1 050 ℃等最佳条件下,利用鄂西铁矿尾矿,可以制备MU20以上标号的普通烧结砖,其烧成制品为红色,颜色一致性好。

Abstract: West Hubei has a large hematite ore reserve, which is a kind of high phosphorous fine-sized refractory oolitic ore. Its beneficiation produces a large amount of hematite tailings that have a fine size, high content of iron which is difficult to recover and low silicon-aluminum content. Their direct disposal can pollute the environment and therefore, a comprehensive utilization of these tailings should be made. Based on the analysis of their basic properties, test research was made on using them to make fired bricks by press-forming. The results show that at the optimal conditions of a 12%~15% forming moisture, 20~25 MPa forming pressure, 950~1 050 ℃ firing temperature, above MU2-class common fired bricks can be made with this kind of hematite tailings, with their fired products having a uniform red color.

Key words: High phosphorous hematite ore, Press-forming method, Fired bricks
