METHODS OF RECOVERING RARE EARTH METALS

A method of recovering a rare earth metal can include incubating a bacterial consortium in the presence of a rare earth metal source comprising a rare earth metal and iron. The bacterial consortium can include an acid secreting bacterium, a heavy metal resistant bacterium, an iron-sequestering molecule secreting bacterium, and a rare earth metal sequestering bacterium. The method can further include: producing an acid using the acid secreting bacterium; leaching iron and the rare earth metal from the rare earth metal source using the acid; protecting the bacterial consortium from metal using the heavy metal resistant bacterium; sequestering iron using the iron-sequestering molecule secreting bacterium; and sequestering the rare earth metal using the rare earth metal sequestering bacterium
