Rare-Earth and Critical Material Recovery from Peralkaline Volcanic Ores: Minerals Processing, Hydrostrict in Labrador, Canada. Minerals such as allanite and fergusonite are found in abundance along with minor chevkinite, bastnasite, and monazite. In some deposits, zircon is present in significant concentrations. The complexity of these materials and the high intrinsic values contained require usi

Rare-Earth Element Adsorption to Gypsum in Hydrometallurgical Processesf these elements. The impurity removal step is a key step in the processing circuit as it can determine the purity of the final product. Lime neutralization is deemed a preferred process due to its high efficiency in the removal of impurities and low reagent cost. However, some drawbacks such as co-

Extraction and Recovery of Rare-Earth Elements and Critical Materials from Coal Waste Using Low Costrite found with REE bearing materials. In the presence of .s, pyrite (FeS.) is used as a source to generate ferric sulfate and sulfuric acid. Such microorganism-based bio-oxidation needs proper conditions for continuous acid generation. In this study, which involved pyrite to generate acid for leach
