Thickener Upgrade Worth Its Weight In Gold

Average thickener underflows have been increased by 4–6% (w/w) – a level that has been set to limit increases in viscosity in the carbon-in-leach (CIL). The 34 m opposition thickener is now delivering a higher average underflow density of 52–54% (often reaching up to 56%) than the 44 m tailings thickener.
