| dc.description.abstract | Deep Sea Manganese nodules are investigated by chemical leaching and solid-state chlorination (SSC) to explore a cheaper processing method. Mn nodules contain various essential elements of cobalt (Co), Nickel (Ni), Copper (Cu), Magnesium (Mg), and Zinc (Zn). The pulverized Mn nodule dissolved in Oxaline (1 oxalic acid + 1 choline chloride) completely within 30 min, and in Ethaline (1 Ethylene glycol + 1 choline chloride) within 72 hours. Also, diluted acids (1M H2SO4 and 1M HCl) leaching with reducing agents (H2O2 or C2H2O4) showed efficient dissolution rates. Furthermore, SSC was effective method to process Mn nodules in a presence of NH4Cl then processed nodules leached in diluted acids. Mn dissolution rate can be ordered at 300 °C (~ 50 %), 600 °C (~ 90 %) without reducing agents. Also, these leaching experiments were carried out with reducing agents and those enhanced the Mn dissolution rate by significant amounts. Finally, leaching solutions processed by the electro winning Mn and Cu are successfully deposited on the electrodes. | |
