A review on complex utilization of mine tailings: Recovery …
Several studies have utilized bioleaching techniques to extract REE from MTs. Reynier et al. [132] investigated the recovery of REEs from tailings collected at restored uranium mine sites in Ontario, Canada. They bioleached the tailings using a combination of native sulfur- and iron-oxidizing bacteria to solubilize the REEs, uranium, and thorium.
