| Abstract Scope |
In order to address the current overwhelming demand for technology metals, advances in extraction methods, and legislations governing production and consumption are essential. For example, the European Commission has created a list of critical raw materials (CRMs) for the EU, including the rare earth elements (REEs), which combine both high importance and scarcity. To supplement the REEs supply in EU, the need for efficient urban mining with innovative recycling processes is strongly promoted.
E-waste is one of the major secondary sources for REEs. The composition of REEs in e-waste vary greatly with the technological advancements from time to time. In this paper, future trends of selected REEs in e-waste and their recovery methods with a focus on carrier metals were examined. The dependence of REEs recovery on carrier metals was statistically analyzed. Large-scale application of selected processes for REEs recovery was investigated. Recommendations for improved REEs recycling were made. |
