针对全尾砂絮凝沉降影响因素多、最优参数计算繁琐的难题，采用均匀设计实验方法，进行多因素影响下絮凝沉降实验研究，探究某矿区全尾砂最佳沉降效果的条件。利用统计软件SPSS进行多元回归分析，得出沉降速率与絮凝剂单耗、尾砂浓度、pH值之间的非线性关系，同时确定了全尾砂最佳沉降参数，实现尾砂高效快速脱水目的。通过研究得出了含泥量高、粒径细的全尾砂的沉降规律，为矿区低浓度尾砂浆的高效利用提供技术支撑。
Abstract：Based on the challenges of the complex factors that affect the flocculation settling of the whole tailings and the tedious process of calculating the optimal parameters, a uniform design experiment method was adopted to conduct experimental research on the flocculation settling of the whole tailings under the influence of multiple factors, aiming to explore the conditions for achieving the best settling effect of the whole tailings in a certain mining area.The statistical software SPSS was used to perform multiple regression analysis, which revealed the nonlinear relationship between the settling rate and the consumption of flocculants, tailings concentration, and pH value.Meanwhile, the optimal settling parameters for the whole tailings were determined, thus achieving the efficient and rapid dewatering of the tailings.The study also investigated the settling characteristics of the whole tailings with high clay content and fine particle size, providing technical support for the efficient utilization of low-concentration tailings slurry in the mining area.
