| 摘 要： | 为了提高某铅锌尾矿的沉降效果,研究了尾矿絮凝沉降特征。以沉降速率及固体悬浮物浓度作为沉降效果的评价指标,探讨了无机絮凝剂聚合氯化铝(PAC)和聚合硫酸铁(PFS)、有机絮凝剂阳离子聚丙烯酰胺(CPAM)和阴离子聚丙烯酰胺(APAM)单独使用以及复配使用后对沉降效果的影响。结果表明,最佳复配药剂组合为PFS-CPAM,无机组分和有机组分最佳质量比为3∶7,最佳用量为80 g/t,此时铅锌尾矿沉降速率为7.69 mm/min,固体悬浮物浓度为46.5 mg/L。

| Abstract: | In order to enhance the settlement of lead-zinc tailings, flocculation and settlement characteristics of the tailings were studied. With the sedimentation rate and the concentration of suspended solids as the evaluation indicators of the sedimentation effect, the influence of the individual and combined usage of two inorganic flocculants (polyaluminum chloride (PAC) and polyferric sulfate (PFS)) and two organic flocculants (cationic polyacrylamide (CPAM) and anionic polyacrylamide (APAM)), on sedimentation effect were discussed. The results show that the best combination of compound is PFS-CPAM, with the best mass ratio of inorganic components to organic components at 3∶7, and the optimal dosage of 80 g/t. In this case, the sedimentation rate of lead-zinc tailings can attain 7.69 mm/min and the concentration of suspended solids can be 46.5 mg/L. |
