Yes this clipping states both autoclaves for an anticipated 2.5Mtpa ore throughput ........

The key features of the autoclaves include:
1. Each of the two autoclaves, weighing approximately 600 tonnes, can manage a slurry
volume of 647m3, which is more than sufficient to achieve the required residence time for an anticipated 2.5Mtpa ore throughput;
2. They operate at slurry temperatures of 250°C and an operating pressure of 4500 kPag,
sufficient to prevent the slurry from evaporating;
3. Turbulence within the compartments of the vessels is maintained by vertical-shaft agitators to ensure mixing of the solids and acid; and,
4. The low pH (acid) slurry necessitates a titanium lining of the autoclaves, to protect the steel shell of the pressure vessel.
