Pressure Oxidation (POX) autoclaves have become the main method to recover gold, copper, nickel, zinc and other metals, but they work with corrosive conditions at elevated temperatures and pressure. For example, a typical gold POX application operates at temperatures of 190 to 230 °C and at pressure of 2.1 to 3.6 MP. In addition, process fluid or slurry containing sulfuric acid is typically used in POX autoclaves.
Consider the challenges of different components of the autoclave and the materials used to construct them, including refractory brick, polymers, titanium, or other corrosion metals. How can you design and engineer a POX autoclave to incorporate the different properties of dissimilar materials?
