The ever increasing move towards high concentration tailings disposal sys-
tems over the last decade has mainly been driven by the need to achieve water
savings. While the technology for implementing high concentration tailings sys-
tems is largely mature, there is a tendency to design for systems for the maximum
concentration tailings that can be produced. This often results in uneconomic
system designs. This paper presents the findings of a study conducted to deter-
mine the optimum concentration for a high concentration tailings transportation
system. The study considers the effects of pipeline length, elevation change, ton-
nage and energy cost. It is recognised that a comprehensive life cycle costing
including all the tailings disposal elements must be performed before selecting the
optimum tailings concentration.
