Abstract. Pelletization is one of useful processes for the agglomeration of iron ore or concentrates. However, manganese ore fines are mainly agglomerated by sintering due to its high combined water which adversely affects the roasting performance of pellets.
Fractionation of iron and manganese, a prerequisite for the origin of ore deposits of either or both elements, is usually attributed to the fact that the solubility of manganese in water is generally higher than that of iron. GEOLOGY – Vol. separated along gradients of pH or Eh in the ocean water column.
Manganese is a silverygray metal and is part of the group known as the transition metals. It is similar to iron. It is hard to melt, but easy to oxidize. Manganese forms chemical compounds in several oxidation states: +2, +4, and +7 are the most common. Manganese compounds can be black, brown, pink, red, green, blue, and purple.

Manganese processing. Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 °C (2,271 °F). Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such as sulfur and oxygen and .
