Abstract

Due to the rapid growth of electrical vehicle and portable electronics markets, huge amount of the rare earth elements(REEs) and lithium have been required for the manufacturers globally. Moreover, after life time of the battery pass, the waste batteries containing valuable metal resources should be recycled due to competitions between the countries who manufacturing the batteries. Therefore, the REEs and lithium recoveries from the e-waste and wastewaters become issue recently. However, the commercialized technology for the valuable metal recovery is limited. In this study, the uses of the REEs and other valuable metal resources such as lithium, uranium, and gold and there recoverying methods according to the different water conditions were investigated and summarized. Moreover, the possible expectations and suggestions for the future application of the valuable resource recovery were conducted as a review.
