Study on the Newly-built Classified Tailings Filling System in a Certain Gold Mine
Taking a classified tailings filling station in a domestic gold mine as the research object,the physical and chemical properties and particle size distribution of the classified tailings were analyzed in depth,and static and dynamic thickening and proportioning strength tests of the classified tailings were conducted.Based on the test results,the appropriate filling process was selected by considering all the factors.The filling slurry was prepared using unclassified tailings,cementitious materials,and water as raw materials.By calculating the filling quantities required in the mined-out area,the required quantities of non-powered deep cone thickeners and cemented filling materials were determined,and the diameter of the non-powered deep cone thickener was set accordingly.By comparing the one-stage mixing and two-stage mixing schemes,the more economical one-stage mixing method was selected for the project.In the comprehensive consideration of the filling process,the importance of factors such as the cost-effectiveness,feasibility,and filling aggregate were emphasized in the scheme,providing useful reference for classified tailings filling.
