Abstract. Three types of low-grade manganese ores belonging to the Pre-Cambrian age are found in the Bonai-Keonjhar belt of Odisha. Out of the siliceous, ferruginous and aluminous Mn-ores the later type was characterised mineralogically and subjected to different physical beneficiation methods such as gravity (heavy media separation, …

It can be observed from this table that the sample contains 42.98 % Fe, 10.69 % SiO 2 and 12.25 % Al 2 O 3.Good amount of MnO 2 indicates presence of some mangangese bearing mineral phases. The complete size analysis of the ROM sample of low grade iron ore fines supplied is given in Table 2.The table suggests that the d 80 of …
