WHAT WE DO
Newmont Leeville Mine, USA
Mine backfill & detailed design, construction assistance, commissioning assistance and training.
P &C carried out detailed engineering, construction assistance, and commissioning of the paste plant and UG reticulation system, including the binder feed system with varying recipe and dosage rates. The plant design enables repulping of previously deposited tailings and the addition of aggregate for improved backfill strength performance. Pulsation dampening on the discharge pumping system alleviated potentially damaging transient events from the S-Tube style positive displacement pump necessitated by the aggregate addition.
KEY PROJECT DATA
Over 10 kilometres of 8-inch diameter paste pipe distribution
