Latest Patents

Kei Yuki holds a patent for a method aimed at recovering metallic tin from electroplating sludge. This method involves leaching the sludge with water at a pH of 7 or less, followed by the separation of iron-containing sludge. The process includes alkalifying the filtrate to deposit tin-containing sludge, which is then separated and recovered. The tin-containing sludge is redissolved in an alkaline solution, leading to electrolytic reduction. This technique allows for the recovery of high-purity metallic tin at a high yield, while also enabling the reuse of other materials without polluting the operational environment. He has 1 patent to his name.
