Electrobioleaching of polymetallic ocean nodules

Hydrometallurgy, 2001
Abstract In this paper, a novel electrobioleaching process for recovering valuable non-ferrous metals from ocean nodules is described. The key for successful and efficient dissolution of copper, nickel and cobalt from ocean nodules depends on prior reduction of the manganese and ferric oxides with which the above valuable non-ferrous metals are ...
