Title: The Innovations of Robert B. Sudderth
Introduction
Robert B. Sudderth is an accomplished inventor based in Tucson, AZ (US). He holds a total of 3 patents that showcase his expertise in metal recovery processes and contaminant extraction techniques. His innovative approaches have contributed significantly to advancements in the field of metallurgy.
Latest Patents
One of Sudderth's latest patents is a process for recovering a metal from an aqueous solution. This method involves contacting a mixed metal chloride leach solution with a water-immiscible solution of a complexing agent. The complexing agent is selective for the neutral chloride of the metal to be recovered, along with a chelating agent that has an affinity for the cation of the metal. The process includes washing the chloride ion from the water-immiscible solution and stripping the chelated metal ion with an aqueous stripping solution to recover the metal.
Another notable patent focuses on the selective extraction of contaminant elements from mixtures. This process improves prior art methods for removing elements such as antimony, bismuth, and arsenic from electrolyte solutions of primary metals. By incorporating an additional step of re-extracting the organic phase with water before precipitating sulfides, the overall process becomes more economical and efficient.
