| Outline of Final Research Achievements |
We have developed environment-friendly recycling technologies that efficiently extract rare metals and precious metals from scrap without generating harmful waste solutions (waste liquids) and exhaust gases. These technologies include: (1) a method for efficiently concentrating and separating platinum group metals in automobile catalytic converters without using harmful acids or other chemicals; (2) a technology for extracting and separating rare metals, such as rhenium, directly from end-of-life turbine blades used in aircraft and power stations without generating any waste aqueous solutions; and (3) a technique for converting contaminated titanium scrap, which is expected to increase in the future, into high-quality titanium feed material. These technologies will help establish an environment-friendly rare metal recycling system.
