| 摘 要： | 针对超细全尾砂难以沉降的问题,本文进行了实验研究.首先进行了不添加絮凝剂的静止沉降实验,实验过程中发现超细颗粒沉降速度较慢;选取砂浆浓度、絮凝剂浓度、pH值和絮凝用量作为影响因素,运用均匀设计的原理,采用U7(74)均匀设计表,进行了添加絮凝剂的沉降实验,并对实验结果进行回归分析.结果表明,添加絮凝剂后的沉降速率要大于... |

| Abstract: | To deal with the sedimentation problem for the ultra-fine tailings,it conducts a series of experimental researches.Firstly,static sedimentation experiments are done without flocculants,to find that the sedimentation speed of fine tailings is really low.According to the uniform design theory,flocculation sedimentation experiments are conducted,using U7(74) uniform design table,choosing tailings concentration,flocculant concentration,pH and flocculant dosage as influence factors,and regression analysis of the... |
| Keywords: | ultra-fine tailings stastic sedimentation flocculation sedimentation regression analysis |
