Journal: Bulletin Of The Mineral Research and Exploration
Year: 2022

In this study, the production technology of rare-earth oxides from Eskişehir-Beylikova complex ore that contains barite, fluorite, rare-earth elements, and thorium were investigated. In this study, processes that can be used in production of thorium-free mixed rare earth oxides were tested. Roasting, leaching, solvent extraction and precipitation methods were used in this study, respectively. Roasting temperature and roasting duration were determined as 600 °C and 1 hour, respectively. The optim
