The cupola is the only furnace type that uses coke as a fuel. Iron is melted by the burning coke and flows down the cupola. As the melt proceeds, new charges are added at the top. The flux combines with nonmetallic impurities in the iron to form slag, which can be removed. Both the molten iron and the slag are removed at the bottom of the cupola.

Manganese Mn is essential to iron and steel production by virtue of its sulfur-fixing, deoxidizing, and alloying properties. Steelmaking, including its ironmaking component, accounts for most domestic manganese demand, presently in the range of 85 to 90 of the total. Manganese ferroalloys, consisting of various grades of ferromanganese and silicomanganese, are used to

Iron And Manganese Removal Publications

Iron and manganese are concentrated in water by contact with certain rocks and minerals, and occasionally man-made materials such as iron and steel pipes. The longer the contact times with the rocks and minerals, the higher the level of concentration. Ground water supplies usually are what require treatment for high levels of iron and manganese.

imparts strength. The amount of manganese used per ton of steel is rather small, ranging from 6 to 9 kilograms. About 30 percent of that is used during refinement of iron ore, and the remaining 70 percent is used as an alloy in the final steel product. Manganese is used also as an alloy with metals such as aluminum and copper.

Manganese Ore An Overview Sciencedirect Topics

Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use manganese ore fines in sinter productions. This would ensure much more consistent manganese content in the hot metal.
