| 摘 要： | 铝土矿选洗过程中排尾形成的高含水量矿泥,传统上采用建库堆存,泌干固结时间长,污染环境。试验研究结果表明,选用由72%水泥、20%石膏、5%石灰、3%硫酸钠组成的复合固化剂,或由72%石灰、20%石膏、5%粉煤灰、3%硫酸钠组成的复合固化剂,按固化剂与矿泥质量比1:10掺加,对矿泥进行固化处理,其固化体强度高、耐久性好,且成本低廉,具有广泛的工程应用价值。

| Abstract: | Traditional disposal of the high water content slime from the beneficiating and washing of the bauxite mine takes a long time to consolidate and causes environment contamination.Experimental results presented in this paper show that compound curing agent made up of 72% cement,20% gypsum,5% lime and 3% sodium sulfate or made up of 72% lime,20% gypsum,5% flyash and 3% sodium sulfate could improve solidification intensity and durability if they were used at a ratio of 1:10(curing agent : slime).Its low cost and environment-friendly merits create a great potential for future application. |
