Thickened tailings loop test to corroborate the hydraulic Hanks model and Buckingham equation
نویسندگان
چکیده
The disposal of diluted tailings in dams, due to their muddy state, becomes inherently difficult contain and this poses a high risk society, as observed the last two accidents that occurred Brazil 2015 2019. Therefore, coarser more relevant because besides contributing reduction water consumption environmental impact, it will also require smaller area. However, transport thicker slurry, viscosity yield stress increase. for long distance conveying systems, friction losses are generated pipeline. In view operating pressures low experience with these pumping is important consolidate hydraulic model used design. loop test setup case was support selected model. Based on data from set up at Brazilian mining company located Iron Quadrangle (Quadrilatero Ferrifero), study proposes validate Hanks & Dadia (1971) using correction according Buckingham equation presented by Abulnaga (2002). test, fine iron ore were pumped positive displacement pumps. varied between 0.013 0.017 Pa.s 31 42 Pa. Very close results actual head loss calculation correction, equation.

The hydraulic transportation of thickened sludges
Industries which pump sludges are under continuous pressure to decrease water content, and increase concentration. Environmentally superior disposal techniques are demanding that such sludges have high mechanical strength properties. This results in a sludge with an increasing viscous character. At high concentration, the viscous forces – which are usually highly non-Newtonian and yield stress ...
