Direct use of manganese fines in the submerged arc furnace (SAF) will lead to the low permeability of the charge, essentially increase the consumption of coke and electric energy. In order to make better use of manganese fines as well as to save energy and cost in the industry, the sintering process of manganese ore is particularly important. In current study, three …

Representative samples of manganese ore sinter for testing shall be drawn in accordance with IS 11607 : 1986. Standard Mark The use of the Standard Mark is governed by the provisions of the Bureau of Indian Standards Act, 1986 and the Kules Regulations made thereunder. The Standard Mark on products covered by an Tndian Standard conveys the ...

Manganese ore smelting is reviewed in terms of processing parameters such as feed material particle sizes, energy input methods, heat transfer modes, smelting …

Manganese ore, which cannot be used directly in the process of production of ferroalloys can be adjusted by removing the volatile substances (moisture and ... materials for sintering are Mn ore fines, fluxes (limestone, dolomite) and fuel (coke, anthracite) [17]. Physical and chemical properties of sintered materials depend on the properties of

To achieve the specific capacity and the yield to be as high as those when coke breeze is only used, the amount of the biofuel for manganese ore sintering should be less than 25 wt.% of the solid ...
