Telfer Gold Project

Australia, WA

Lycopodium provided engineering design, procurement and construction management (EPCM) services for the processing facilities to treat 18 Mtpa of open pit and underground ores to produce copper concentrates and recover precious metals on site.

Extreme climatic conditions and remoteness of the site was reflected in the design and implementation approach.
The Project was undertaken as a joint venture between Minproc, Hatch and Lycopodium.

The flowsheet for Telfer included the following:

  • Two process trains, each with a capacity of 9 Mtpa
  • Primary crushing facilities for open pit ores
  • Transfer conveyor for underground ore
  • Primary crushed ore sampling
  • Crushed ore stockpile stacking via luffing and slewing radial stacker (3 units)
  • A grinding facility comprising one 15MW SAG mill and one 13 MW ball mill in closed circuit with classifying cyclones for each process train
  • Pebble stockpile and recycle crushing facility
  • Gravity gold concentration via Falcon centrifugal concentrators
  • Two-stage flash flotation circuit
  • Copper and pyrite flotation comprising roughing, scavenging, cleaning and recleaning cells, with provision for controlled potential sulphidisation (CPS)
  • Screening, thickening, pressure filtration and stockpiling of copper concentrate
  • Load-out facility for road transportation of copper concentrate
  • Pyrite concentrate desliming, thickening and filtration
  • Pyrite leaching and CCD thickening
  • SART/AVR cyanide recovery
  • Reagent Mixing for CPS, flotation, CIL and SART reagents
  • Flotation tailings thickening and disposal.
