A typical gold beneficiation flow sheet: a brief overview

  • As ore is transported from stockpile along a conveyor belt, an overbelt magnet removes ferrous-based junk from the stream.
  • Following screening, the stream can be sampled with Multotec’s hammer sampler.
  • A semi-autogenous or ball mill then grinds and crushes the ore to a finer particle size, which is then fed to a trommel screen.
  • Cyclones are then employed to separate correctly-sized particles from oversized particles, with oversized particles being returned to the mill for further crushing. Correctly-sized particles can be transported to a thickening dam, ready for leaching.
  • A slurry sampler is usually installed prior to the addition of cyanide-based solution in the leaching process. Kambalda screens and Interstage screens are used within the CIP/CIL process. Screens are also placed prior to flotation as well as in the elution outflow.

* NOTE: Multotec now offers an enhanced gold-selective ion exchange resin, enhancing gold recovery by up to 25% over carbon-based leaching. Read more about Clean-iX® for gold recovery here.

  • Flotation screens are used in the gold beneficiation process to isolate copper particles to Cyclones are used further in the discharge of tailings within the slime dam.
