Abstract
The marine nodules are an attractive alternative source for the extraction of manganese due to the scarcity of high-grade metals on the surface. In the present investigation, working parameters (Fe2O3/MnO2 ratio and sulfuric acid concentration) were optimized for the dissolution of Mn from marine nodules using foundry slags. Finally, it is concluded that the optimum MnO2/Fe2O3 proportion is 1/2, while the optimum concentration of H2SO4 is 0.3 mol/L for a leaching time of 20 minutes achieving solutions of 70% Mn.
