A brief overview of a typical gold processing flow sheet

1. Once loaded on a conveyor belt, an overbelt magnet removes ferrous-based junk from the ore.

2. The ore is then ready for preliminary screening. Downstream of this screening, the stream is sampled with a hammer sampler.

3. A semi-autogenous or ball mill is then used to grind and crush the ore to a smaller particle size. Downstream of the milling, the stream is fed to a trommel screen.

4. Cyclones are set at the appropriate cut point to separate correctly-sized particles from those that are too large. Oversized particles are returned to the mill for further crushing. Correctly-sized particles can be sent to a thickening dam for leaching.

5. Normally, a slurry sampler is installed prior to the addition of cyanide-based medium 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 a new gold-selective ion exchange resin that enhances gold recovery by up to 25% compared to carbon-based leaching. Read more about our Clean-iX® for gold processing recovery here.

6. Flotation screens are further employed to isolate any copper particles. Cyclones are used further in the discharge of tailings within the slime dam.
