摘要
硫酸浸出过程是蛇纹石综合利用过程中的关键因素之一 ,在单因素条件实验的基础上 ,采用 L16( 4 4)正交实验法对蛇纹石硫酸浸出过程的优化工艺条件进行了研究。结果表明 :当以矿粒粒径 <75μm、搅拌速率 >2 0 0 r/min、活化剂 FS-1加入量为 1.5 %为固定因素时 ,其优化工艺条件为 :浸出温度 10 0℃ ,浸出时间 3h,硫酸质量浓度为 45 % ,液固比 4.0。
The leaching process of serpentine in sulfuric acid is one of the key factors in the comprehensive utilization of serpentine. In this paper, based on the previous results of separate factor conditional experiments, the optimum technological conditions during the leaching process of serpentine in sulfuric acid are studied by using orthogonal L 16(4 4)experiments. The results indicate that,when the particle size is less than 75 μm,the stirring rate more than 200 r/min and the amount of activating reagent 1.5% and these factors are taken as invariable factors, the optimum technological conditions are as follows:the leaching temperature 100 ℃,the leaching time 3 h, the concentration of sulfuric acid 45%,and the proportion of liquid to solid 4.0∶1.
