Biomining for sustainable recovery of rare earth elements from mining
The first stage involves the use of acidophilic iron, and sulfur-oxidizing microbes to extract base metals, and the second stage involves the solubilization of rare earth and precious metals (Magoda and Mekuto, 2022). Biomining technologies are also scalable, which allows for varying amounts of REEs to be extracted.
