Abstract:
Hydrometallurgical processes can be exceptionally corrosive. Operating conditions associated with metal extraction and refining require materials of construction that can withstand process acids and acid chlorides at temperatures up to 90°C. Process vessels, piping, scrubbers and ducting can be rapidly compromised in these aggressive environments if not designed with great care. Design engineers are frequently challenged to find materials of construction that can stand up to hydrometallurgical processes especially for copper, zinc, nickel, cobalt and uranium. This paper will evaluate a variety of material solutions to determine which provide attractive economics for initial procurement as well as high durability for reasonable life cycle costs. The comparative cost and durability information presented is intended to enable design engineers and material specialists to choose materials of construction that will be the most beneficial for their projects.
