Title: Roald R Skarbo: Innovator in Solvent Extraction Processes
Introduction
Roald R Skarbo is a notable inventor based in Lexington, MA (US). He holds 2 patents and has made significant contributions to the field of solvent extraction processes, particularly in the recovery of metals from aqueous solutions.
Latest Patents
Skarbo's latest patents include a selective solvent extraction process for copper from nickel. This invention relates to a method for selectively recovering copper from an aqueous solution containing both copper and nickel, with a pH above about 9. By using limited amounts of oxime, the process allows for the preferential extraction of copper ions over nickel or cobalt in a multistage countercurrent process. The hydrogen ion of the oxime molecule exchanges with the copper ion in the aqueous solution, facilitating this selective extraction.
Another significant patent involves the removal of ammonia from solutions of oxime-metal chelate. This process selectively removes ammonia from an organic solution containing ammonia and an oxime-metal chelate by countercurrently contacting it with an aqueous solution of ammonium carbonate or bicarbonate. The method ensures that the ammonia transfer occurs efficiently while maintaining the necessary concentrations to prevent emulsification.
