ABSTRACT

There is today an interest to apply paste technology for surface disposal in the base metal, gold mining, and oil sand sectors. Pipeline loop experiments at the GIW Hydraulic Testing Laboratory with an open shrouded and augered centrifugal pump (impeller diameter 0.3 m) showed that a simulated paste product could be pumped at yield stresses well over 200 Pa. The feasibility of different pumping systems is briefly discussed.
