Progressive Cavity Pumps for Mining Tailings

Controlled positive-displacement transfer for thickened tailings and abrasive mineral-process streams containing high concentrations of suspended solids.

Tailings Transfer

Positive displacement for dense mineral slurries

Tailings duties can range from relatively dilute process water mixtures to highly concentrated thickened slurry. Progressive cavity pumps can provide predictable displacement at controlled speed, making them useful where slurry viscosity, solids concentration or changing system resistance creates difficulty for conventional centrifugal equipment.

AbrasionMineral particles, sand and fines
Variable speedControlled capacity adjustment
PressurePositive-displacement transfer against system resistance
Selection Framework

Solids characteristics determine more than capacity

Particle hardness, concentration and size distribution affect wear, while slurry rheology and settling tendency influence suction performance. Selection should consider the complete operating envelope, including startup conditions and the highest expected solids concentration.
