“…The initial and main technological operation of preparing the filling mixture is the thickening of the slurry coming after the technological process of ore beneficiation [30][31][32]. In the practice of mining, various thickeners are used, differing in design and mode of action: radial, hydrocyclones, centrifuges, etc.…”

“…The consumption of clarified water and the content of solid particles in it were measured. To measure the distribution of the concentration of solid particles along the height of the thickener (along the height of the vertical part), holes 10 mm in diameter were drilled in the casing, through which pulp samples were taken into special calibrated containers [30]. After sampling, the holes were plugged with plastic plugs.…”

The issue of the influence of the concentration of the solid phase on the reduction of energy costs and specific energy consumption during pulp transportation is considered. The procedure for preparing slurry from the current enrichment tailings is shown. A scheme is given and the operation of a hydroficated unit for thickening and hydraulic transport of backfill mixtures is described. A diagram of the movement of solid particles in one of the units of the complex – a lamellar thickener is shown. The summary table shows the main design parameters and characteristics of the lamellar thickener. A general view of the laboratory setup used for experimental studies with slurry at various concentrations is given. An example of calculating productivity, density and specific load is presented. The dependence of the shear stress on the velocity gradient was determined for various pulp concentrations. Experimental studies of the process of thickening the production of slurry from the current enrichment tailings have been carried out. It was found that the geometric dimensions of the thickener depend on the concentration of the solid phase in the transported mixture. It is concluded that the flow rate of the slurry and the head loss are functions of the rheological characteristics of the viscoplastic slurry and can be calculated from the derived calculated dependencies.
