Reductive leaching of manganese from low grade manganese

The results showed that high manganese recovery with low Fe and Al extraction yield could be obtained by analyzing the leaching efficiencies of Mn, Fe and Al during the leaching process. The optimal leaching condition was determined as 1.9 mol/L H 2 SO 4 and 60.0 g/L cane molasses for 120 min at 90 176;C while using particles smaller than 0.147 mm.
