2015-4-10 · Lump ore from Azul has a 47.7% level of Mn and an Mn/Fe ratio of 13.3. Pellets have a higher concentration of Mn (50,9%), but a lower Mn/Fe ratio (6.8). Lump ore from Azul is rich in hydrated manganese minerals (todorokite and n-sutite). There is a significant occurrence of manganese oxides (cryptomelane and pyrolusite) and iron (magnetite).

CHAPTER 1 MINERAL DRESSING

The ore lumps from the mines have the lump size of 10 - 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments.
