Paste and thickened tailings are increasingly recognized as alternatives to the
conventional solutions of tailings dams and mine backfill for handling mineral
tailings and for water recovery. Designing and implementing a flowsheet for pro-
ducing paste with a thickener requires integrating the thickening, transportation,
and disposal designs. In addition to the physical parameters of flow rates and
density, a proper paste system involves matching rheologies between these three
phases of the flowsheet. This paper focuses on the practical application of design-
ing a paste system. Case studies are presented which show how a tailings han-
dling system, using a paste thickener, are designed based on actual developing
