Abstract

A recent theoretical model of the subaerial deposition of mine tailings slurries predicts that the profile of a tailings delta formed with constant inputs will conform to an exponential curve. Both the profiles of and the particle sorting on one platinum and two coal tailings deltas have been shown to conform to the theoretical model, as have the profiles of three laboratory coal talings deltas. The profiles of a further eight metalliferous and two coal tailings deltas, with a wide range of input tailings parameters, are shown here also to conform to the exponential curve predicted by the theoretical model.
