The Goldstrike Autoclave Plant Design, Commissioning And Operation

The Goldstrike autoclave plant is designed for the pressure oxidation of 1363 t/d (1500 stpd) of refractory gold ore. The plant was commissioned in early February 1990 over a one week period - an unusually short period for a plant of this complexity. The rapid plant start-up is attributed to certain detailed design and control aspects of the plant. This paper discusses key features of the autoclave plant with emphasis on the design of the splash/flash system of heat recovery and the control systems. Commissioning and plant operations over the first three months are reviewed.
