We apply our expert understanding of complex hydraulics and tailings disposal to develop economical and environmentally feasible solutions that result in longer design lives, reduced failure risk and increased efficiency.

We specialise in the design of tailings management systems that couple innovative design approaches with the latest materials for the effective recovery, reprocessing and relocation of tailings. Our solutions include:

Conventional Tailings Management

  • Cyclone sand separation and distribution
  • Single point discharge
  • Perimeter spigotting
  • Open channel flow (launder system)
  • Drop box systems.

Deep Sea Tailings Placement (DSTP)

Water Delivery and Reclaim Systems

Paste and Thickened Tailings

Ash Management

  • High concentrated slurry disposal (HCSD)
  • Fly ash, bottom ash
  • Central ramp discharges
  • Side hill discharges.

Control Systems - SCADA, System Integration and Automation
