Latest Patents
John D Prater holds a patent for the "Recovery of copper from arsenic containing metallurgical waste materials." This patent focuses on processing highly toxic metallurgical waste materials from copper smelting and refining operations. The method involves a cyclic process that recovers copper values while minimizing environmental contamination. The waste materials, primarily consisting of arsenic, bismuth, lead, antimony, and cadmium, are treated in an autoclave under an overpressure atmosphere of oxygen. The resulting solution, which is rich in copper, undergoes cementation on metallic iron to recover copper and eliminate toxic constituents without producing arsine gas. The process ensures that the copper-barren solution can be recycled, and the cement copper precipitate can be smelted with copper ore concentrates.
