  • To investigate the necessity and background of the metal recycling from urban mine resources, 4 bigger problems such as the limitation of the underground resources, consumption of the metal resources, contamination of environment and metal recycling business were reviewed. Waste management and recycling are the foremost issues facing Korea on its path to sustainable development in the 21st century. Especially, metal recycling from urban mines is the most urgent fact for global environment and resources conservation. In order to build a recycling-oriented society, it is necessary to develop the recycling technology, recycling practices and a recycling-oriented economic system.

  • Car exhaust $CO_2$ gas reduction and fuel efficiency of the car lighter for the current era is a big challenge. The developments of high-performance Nd magnets, Li-ion secondary battery and exhaust gas purification performance of PGM catalysts used in the lightweight EV and HEV are activated. Country in order to improve the car lighter and function that use the resources of rare metals are ubiquitous imported from China because of export supply control, as soaring prices have unstable supply and demand. Compared to the emissions from the next-generation automotive recycling, waste scarce resources need to be. This study investigated the recycling technology analysis and development of the information technology, or delivered to the researchers by giving national car industry aims to contribute to the development. Findings, pulmonary high-performance motor vehicle emissions in the exhaust gas purification PGM Catalysts, Li-ion battery and Nd magnets recycling technology, such as pre- and post-processing techniques to classify technology, pre-urban mining technology mechanical separation by screening techniques under development, the study and post-processing technology has, pyro and hydro metallurgical smelting technology is established. Waste Recycling in terms of economic efficiency of mechanical components for the intensive study of screening techniques is needed.
