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.
