      Efficient extraction of Ni, Co, Cu, and Mn from low grade and refractory ores is a common technical challenge. The present study proposes an Acidithiobacillus ferrooxidans coupled leaching of Ni, Cu, Co, and Mn from oceanic polymetallic nodules and low grade nickel sulfide ore, and focuses on the electrochemical behavior of the ores in simulated bio leaching solutions.
