Title: E Michael Kerr: Innovator in Metal Extraction Technologies
Introduction
E Michael Kerr is a prominent inventor based in Aurora, IL (US), known for his significant contributions to the field of metal extraction technologies. With a total of 11 patents to his name, he has developed innovative methods that enhance the efficiency of extracting precious metals from mineral resources.
Latest Patents
Among his latest patents is a groundbreaking method titled "Polymeric combinations used as copper and precious metal heap leaching." This invention presents an improved technique for extracting precious metals from mineral fines through heap leaching with dilute sulfuric acid. The process involves agglomerating mineral fines using a specific composition of polymers, which includes a first polymer from the group of anionic and nonionic water-soluble polymers, followed by a second cationic water-soluble polymer. Preferred first polymers include poly(acrylamide) and a 70/30 mole percent blend of poly(acrylamide/sodium acrylate). The second polymers are selected from poly(diallyldimethylammonium chloride) and other specific blends.
Another notable patent is "Opposite phase entrainment reduction in solvent," which addresses the challenge of reducing the entrainment of aqueous mineral acid solutions in organic extractants during the solvent extraction of metals. This method involves adding a water-soluble cationic polymer to the metal-rich aqueous mineral acid solution before mixing it with a metal-poor organic extractant. The result is a more efficient separation of phases, particularly beneficial in copper extraction.
