Latest Patents
One of Sugawara's latest patents is a process for recovering tellurium from copper electrolysis slime. This innovative method involves leaching copper and tellurium from the slime using sulfuric acid. The tellurium is then recovered from the leach solution by suspending copper electrode plates in the bath, allowing tellurium to deposit as copper telluride. This process not only enhances the recovery of tellurium but also produces a high-grade copper tellurium precipitate.
Another significant patent is an apparatus and method for manufacturing a copper-base alloy. This invention includes an alloying spout, at least one feeder, and a tundish that is inclined to facilitate the flow of molten copper. The method allows for the continuous introduction of solid solute constituents into the molten copper, resulting in a well-mixed copper-base alloy.
