Values of head loss for a high concentration copper tailings slurry have been obtained from an ad hoc experimental rig (concentration up to 42%Cv (solids by volume), adverse (positive slope) of 8%). Measured data permits the calculation of the ratio Z, defined as the head loss of mixture for a θ angle /head loss of mixture for θ = 0. This ratio yields a value of 1.11 with a standard deviation σZ = 0.04. }, doi={10.36487/ACG_repo/963_21}, url={https://papers.acg.uwa.edu.au/p/963_21_Bernal/} }
