Scope Book. The preheated and thickened ore slurry is pumped by a single stage centrifugal pump (215- PPS-009/010, duty/stand by) from the autoclave feed tanks to the heater section of the intermediate temperature (IT) heater/flash vessel (220-PRV-112, 4,020mm heater PD x 16,550mm tan/tan). Steam from the integrated intermediate pressure flash vessel (3600mm PD) heats the slurry. Slurry discharges the IT heater at 151°C and is transferred by three stage centrifugal pumps (220-PPS-115 to 120, duty/standby sets) to the heater section of the high temperature (HT) heater/flash vessel (220-PRV-113, 4,160mm heater PD x 17,430mm tan/tan), where it is heated by steam from the integrated high-pressure flash vessel (3654 PD). The heated slurry at 200°C is then pumped into the autoclave via a live steam trim direct heater (220-PRV-114, 2,500mm PD x 5,400mm tan/tan). Two high-pressure positive displacement pumps (220-PPD-101/102) operating in parallel are used to transfer the slurry from the HT heater discharge through the trim heater to the autoclave. The trim heater raises the slurry temperature to 259°C. The autoclave feed density is reduced by contact with condensing steam to 27.6% solids by weight. The slurry is leached with H2SO4 at an approximate ratio of 122kg acid for each tonne of ore, in a six-compartment autoclave (220-ALV-100, 4,300mm PD x 25,845mm tan/tan) at high pressure (5,900kPa) and high temperature (270°C). Sulphuric acid is delivered to each of the first three autoclave compartments using one positive displacement high-pressure acid pump (220-PPD-003/004/005) for each compartment. Sulphuric acid is fed directly to the pump suctions from the sulphuric acid storage area (Area 330). The nominal H2SO4 deliveries to the first, second, and third compartments of the vessel are 25m3/h, 7.2m3/h and 3.6m3/h, respectively. The slurry/acid mixture cascades through the six agitated compartments of the autoclave. Dual impellers driven by 75kW motors agitate each of the first three compartments; 37kW motors drive the agitators in each of the final three compartments. Complete dissolution is required to maximise liberation of nickel and cobalt as sulphates. Slurry residence time in the autoclave is 30 minutes. Nickel and cobalt extractions from the ore into solution are approximately 94.5% and 93.5% respectively. The leached slurry discharges the final autoclave compartment at 270°C and 22% solids by weight. Each agitator shaft is equipped with a cartridge type, dual-pressur...
