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.

2008-3-26 The manganese ores in the Santa Rosalía region, western Mexico, are mostly hosted in the Boléo Formation (Fig. 1), a marine-clastic sequence of upper Miocene age. The manganese mineralization is related to northwest- to southeast structures, and it mostly occurs as stratiform horizons or mantos, which are restricted to isolated basins.

2020-4-25 Manganese ore samples have been divided into Mn-rich and Fe-rich manganese ores. 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.
