Title: Roald R Skarbo: Innovator in Liquid Ion Exchange Processes
Introduction
Roald R Skarbo is a notable inventor based in Lokken Verk, Norway. He has made significant contributions to the field of chemical engineering, particularly in the recovery of metals through innovative processes. With a total of 3 patents to his name, Skarbo's work has had a substantial impact on the industry.
Latest Patents
One of Skarbo's latest patents is focused on the scrubbing of ammonia from oxime liquid ion exchange reagents. This process is designed to scrub extracted ammonia from oximes, making it particularly adaptable as a secondary scrub prior to acid stripping. The method effectively eliminates the pH rise of the aqueous scrub liquor that is typically associated with acid scrubbing. By utilizing extractable metal sulfates in an aqueous scrub solution at a pH of less than 7, the process allows for an exchange of ammonia on the oxime for copper or nickel, resulting in the formation of ammonium sulfate without altering the pH of the aqueous scrub solution.
Another significant patent involves a liquid ion exchange process for the recovery of copper and nickel. In this process, ammoniacal leach solutions containing nickel and copper are treated by first extracting copper, leaving nickel in the raffinate. The nickel is then extracted with an organic extractant, which is subsequently stripped with a concentrated ammonium salt solution. This innovative approach prevents the buildup of copper in the nickel extraction circuit by recycling part of the organic from the nickel strip circuit back to the copper extraction circuit.
