Up to 5% of the gold particles liberated using a disc mill were coated with iron due to smears from the grinding surfaces. Based on shape-factors, the efficiency of subsequent gravity concentration operations increased in the order of flakes < cigars < spheres. A proposed flowsheet increased the gold extraction by over 15%.

A flowsheet with mill design parameters was developed that consisted of (1) free gold and scheelite recovery by gravity methods and froth flotation and (2) fine-grained gold recovery by cyanide leaching of reground gravity and flotation tailings, followed by a carbon-in-pulp (cip) circuit.

improve recovery. Free-Milling Gold Low Grade In the case of low grade (< 1 g/t) free-milling gold deposits, the ore is often crushed and heap leached. While the recoveries are typically lower than what would be obtained with a conventional gravity-cyanidation flowsheet, the savings in CAPEX and grinding costs often justify this route. When ...

Gravity recovery will be better quantified by conducting E-GRG tests which simulate gold liberation in a grinding circuit at different sizes. Past testwork indicates that a gold recovery of up to 95% may be possible with a more complex flowsheet which would include grinding, gravity…

Leach gold recovery (in %) = 95.07 – 8.74/Head grade (in g/t) When the gravity and the leach gold recoveries are combined, and then reduced with the typical plant losses or impact of scale up of gravity recoverable gold for plant operating conditions (typically about 0.8%), the following net recoveries are obtained:

Both streams contain a gravity gold recovery circuit. Approximately 40% of the gold at Telfer is produced as doré which is smelted on site.
