Title: Yukie Kawakami: Innovator in Rare Earth Element Recovery
Introduction
Yukie Kawakami is a prominent inventor based in Ehime, Japan. She has made significant contributions to the field of materials science, particularly in the recovery of rare earth elements. With a total of 3 patents to her name, her work focuses on developing efficient and cost-effective methods for extracting valuable metals.
Latest Patents
Kawakami's latest patents include a method for recovering rare earth elements. The objective of this invention is to provide a technique that allows for the efficient recovery of rare earth elements with a high recovery rate, without the need for expensive chemicals or solvents. This method involves allowing a water-soluble salt, other than sulfate ions, to coexist with an aqueous solution containing a rare earth element. Subsequently, an alkali metal sulfate is added to produce a precipitate of a double sulfate of the rare earth element.
Another notable patent is her valuable metal leaching method, which also includes a valuable metal collection method employing the leaching technique. This invention enables the efficient leaching of valuable metals while minimizing the amount of reducing agent used, thus achieving cost reduction. In this process, a positive electrode material is immersed in an acidic solution alongside a metal with a lower reduction potential than hydrogen, allowing valuable metals to be leached from the positive-electrode active substance.
