ADVANCED MATERIALS & PROCESSES | MAY/JUNE 2024 7 group metals. The system then streams the dissolved electronics and ores over specialized electrodes in three consecutive extraction columns designed for oxidation, leaching, and reduction. An economic analysis of the approach shows that the new method costs substantially less than current industrial processes. According to researcher Xiao Su, one of the many advantages of the new method is that it can run continuously in a green fashion and is highly selective in terms of how it extracts precious metals. “We can pull gold and platinum group metals out of the stream, but we can also separate them from other metals like silver, nickel, copper, and other less valuable metals to increase purity greatly—something other methods struggle with,” says Su. The team is now working to perfect their new process by improving the engineering design and the solvent selection. illinois.edu. URANIUM MINERAL DATABASE A first-of-its-kind dataset and corresponding analysis has been published by nuclear nonproliferation scientists at the DOE’s Oak Ridge National Laboratory (ORNL) in Tennessee. The Compendium of Uranium Raman and Infrared Experimental Spectra, or CURIES, is a public database and analysis of structure-spectral relationships for uranium minerals. It fills a key gap in the existing body of knowledge for mineralogists and actinide scientists. Laser-based vibrational spectroscopy methods such as Raman and IR are frequently employed by nonproliferation materials scientists because they are rapid, nominally nondestructive, and can give direct insight to what a material contains. Where spectral assignments may be difficult, the CURIES database uses structural information, subject matter expertise, and statistical analysis to determine key features of Raman spectra based on their structural origins. The ORNL team hopes that CURIES will support researchers who are looking for new relationships among various types of uranium materials and foster development of rapid characterization and analysis of spectra collected on new materials. ornl.gov. The CURIES database will help researchers better identify uranium samples. Courtesy of Tyler Spano/ U.S. Dept of Energy.
