About this Research Topic
The technological development experimented in the last decades is remarkable. Undoubtedly, technology is present today in several aspects of our daily life. The enhancement of several devices containing metals has contributed to improving their final properties. However, natural resources to obtain metals are exhaustible. An interesting alternative to guarantee the sustainable use of these critical metals is the development and improvement of several technologies that involve processes to recover and recycle them from devices when their useful life is ended. In this way, it is possible to reuse these metals for different applications. Advances in technologies related to this topic are of great interest nowadays.
It is known that certain metals are considered crucial due to their great importance for several applications in different fields. The steadily growing demand for these metals leads to a worldwide concern, because the natural sources to obtain them are scarce. For this reason, the investigations about processes and techniques to recover these strategic metals are nowadays an important aim to the scientific community. Nowadays, various technologies are being investigated to recover efficiently several strategic metals by both, pyrometallurgical (calcining, roasting, or smelting) and hydrometallurgical (leaching, solvent extraction, or ionic exchange) processes. Among other technologies, advances in processes and technologies to recover strategic metals could provide interesting information on this topic.
This Research Topic aims to collect a large range of contributions concerning different aspects (but not limited to) on "Advances in recovery technologies of strategic metals". A wide range of descriptions of different technologies and processes for strategic metals recovery is desired. In addition, the assessment of the characterization and the final properties of these recovery metals would be of interest. Original Research, (critical) Reviews, Tech and Code, Methods, Mini-Reviews, and Perspectives that focus on this goal are equally welcome.
Keywords: strategic metals, recovery, processing, separation, characterization
