Raw Material Characterization And Reductive Leaching Of Low Grade Manganese Ore With Bamboo Sawdust In Sulphuric Acid

This research used two types of raw materials which are synthetic manganese ore and low grade manganese ore. The characterization analysis of raw materials was determined via morphological study and phase identification. The results showed synthetic manganese ore is high grade with 34.32 % Mn and th...
