2015-6-16  The manganese ores, collected from different mines are megascopically examined and found to be largely com-posed of pyrolusite, psilomelane-cryptomelane and wad. A small amount of jacobsite also occurs associated with the ore. There are also some iron ores like ferruginous laterite and ochres (Table 1) show the capping of manganese deposits.

Average major elements contents (wt.%) of Mn-rich and Fe-rich manganese ore samples and their host rocks are compared in Fig. 5a. Mn-rich ores are higher in MnO and lower in Al 2 O 3, Fe 2 O 3 and SiO 2 than Fe-rich ores.
