| 摘 要： | 对铝土矿尾矿进行絮凝沉降实验,研究絮凝剂种类及用量、助凝剂种类对铝土矿正浮选尾矿矿浆沉降行为的影响。研究表明PAC、PAFC、PFS作为絮凝剂使用时,虽然出水较为澄清,但是沉降速度过慢;而PAM作为絮凝剂使用时,沉降速度快,絮团紧实,具有很好的实际应用性,0.5、1、1.5h澄清液面高度分别为:7.2、7.5、7.7cm,主要沉降作用发生在0~0.5h阶段。PAC、PAFC、PFS作为助凝剂与PAM配合使用时,具有较好的絮凝效果,能互相弥补彼此缺点,0.5、1、1.5h澄清水位高分别为3.5、5.1、5.6cm,PFS用量为300mg/L的时候,SS为最小值265mg/L,与单独使用PAM10mg/L相比SS下降了约180mg/L。

| Abstract: | The component of desulfurizer had a great influence on the desulfurization perfor- mance. How to accurately measure the composition and content of calcium compounds in cal- cium-based desulfurizer was always a major problem in the analysis field. The composition and content of calcium compounds could be determined by measuring the calcium oxide, free calcium oxide and loss on ignition of desulfurizer. After repeated verification, the results showed that the method was accurate, feasible and widely applicated in the determination of the effective component in calcium-based desulfurizer. |
