SIZING CONSIDERATIONS FOR ACID BRICK LINING SYSTEMS FOR LARGE HYDROMET PROCESS VESSELS

摘要

Acid resistant brick lined vessels are utilized in pressure leaching and pressure oxidation for copper, nickel, gold and other metals. As lined vessels in hydrometallurgical processes continue to increase in scale to improve project economics, the maximum allowable size becomes a design consideration. Acid brick linings are installed in conjunction with chemical resistant membranes between the brick lining and the vessel shell. The chemical resistant membrane limits the use of anchoring systems commonly used in pyrometallurgical applications. The properties of the acid brick lining and the process must be considered when selecting the vessel size and configuration during the early design stages of a process plant.
