An Introduction to the Chemistry of Metal Extraction
WebJul 1, 2024 · The goal of the present study was to extract rare-earth elements from silicate-based ore. Due to the increasing interest in such elements and the control of fewer countries of their extraction, the search for new resources is necessary. There is a lack of studies in the literature on the extraction of rare-earth elements from silicates ores. WebAug 14, 2024 · Extracting desirable elements without co-extracting undesirable ones means less waste is created that will need downstream treatment and disposal. Supporters of the work include DOE’s Critical Materials Institute, or CMI, for separations research and DOE’s Office of Technology Transitions, or OTT, for process scale-up.
