摘要/Abstract

摘要： 为探究全尾砂絮凝沉降条件下立式砂仓面积最佳计算模式，根据最理想沉砂条件和不同沉砂特点，从3种计算模式中确定出结果误差最小者.以某铅锌矿为例，进行细粒级全尾砂絮凝沉降试验，回归分析得到最佳沉砂条件下的沉降曲线，依此从3个角度分析立式砂仓面积计算模式的可靠度.最佳絮凝条件:相对分子量为8×10⁶的阴离子聚丙烯酰胺(APAM)，入料砂浆体积分数为7.80%，对应的絮凝剂单耗为17.66g·t^-1.最佳立式砂仓面积为36.06m²，托麦吉-菲契图解计算模式所得结果与其贴近度达97.04%.

Abstract: In order to explore the optimal calculation mode of vertical sand silo area under the condition of flocculating sedimentation of unclassified tailings， the minimized result error was determined through 3 calculation modes based on the ideal sedimentary condition and the different sedimentary characteristics. Took the case of a lead and zinc ore as an example: the flocculating sedimentation tests of fine unclassified tailings were conducted， then the slurry settlement curves under the best settling condition were obtained by regression analysis. The reliability of calculation modes for vertical sand silo area was analyzed. Results showed that the best flocculent condition is as follows: the relative molecular weight of APAM is 8×10⁶， the volume fraction of feeding slurry is 7.80% and the appropriate unit consumption of flocculants is 17.66g·t^-1. The optimal area of vertical sand silo is 36.06m²， which is 97.04% close to the result based on the Talmage-Ficth graphical method.

Key words: unclassified tailings, flocculating sedimentation, vertical sand silo area, regression analysis, calculation mode
