Measurements and observations from bench- and pilot-scale flume and shear cell testing of nonsegregating tailings (NST) are incorporated into a semi-empirical analytical model for the prediction of fines segregation for various deposition
methods and tailings characteristics. The model allows exploration of the effects of tailings mixture characteristics and tailings placement scenarios on fines capture, and enhances tailings basin management planning. This paper presents: 1. the theoretical basis of the analytical model ; 2. an evaluation of the capability of the model to predict the results
observed in flume tests ; 3. predictions of fines capture for schematic tailings basin configurations representing an external tailings facility and an in-pit disposal area.
