In-Situ Bioleaching of Manganese by Dissimilatory Reduction
Project Innovation + Advantages:
The proposed project will develop a reductive bioleaching process, using bacteria to recover manganese from low-grade U.S. ores. Manganese is key to several common battery technologies, with no substitutes in its major applications. It has not been mined in the US since the 1970s. The mining technology is a major departure from conventional manganese mining because it allows manganese extraction without significant environmental disturbance or the use of toxic chemicals.
