| Research Abstract |
The following new rare metal separation techniques including selective crushing, physical separation and chemical treatment have been studied for recycling. The parts control by observing with RFID, the sorting technique using Raman spectroscopy, the selective material crushing using underwater explosion and mechanical crushing, the recovery of Cu by carbonization of printed circuit board with removal of Br and the Ta and Ni recovery from capacitor as electronic parts using physical separation and heat treatment, the Co and Li recovery from lithium-ion battery, the W recovery from used cemented carbide, the In recovery from liquid crystal display, the zircon recovery form polished powder, the recovery of rare earth and B using adsorption techniques have been developed. Some parts are compared with the conventional technology and the utilization in the recycling-oriented society is investigated.
