The Rheological Property Study on the Slurry of Unclassified Tailings Cemented for an Iron Mine

Abstract There is a large iron mine deposit in Anhui province, the mining and dressing ability was designed to 4.5 million t/a, the main mining method is stage open stoping with subsequent filling and the filling ability is 100m3/h. The experiment process of rheological property for the slurry of unclassified tailings cemented will be shown in this paper. By the experiments of diffusion degree and viscosity test for slurry with different concentration and sand-cement ratio were carried on, the relation between rheological property of the slurry and ratio parameters can be got. The experimental results effectively evaluate the rheological properties of the filling slurry; the ratio parameters of filling material which were accordant with the requirements of the mine filling process about the filling slurry pipeline can be provided.
