Ferro-manganese (Fe-Mn) is an important additive used as a deoxidizer in the production of steel. It is a master alloy of iron (Fe) and manganese (Mn) with a minimum Mn content of 65 %, and maximum Mn content of 95 %. It is produced by heating a mixture of the oxides of Mn (MnO2) and iron (Fe2O3) with carbon (C) normally as coke or coal.

New technology is developed for preparing pure vanadium pentoxide from vanadium-containing metallurgical slag. As a result of the selective extraction of vanadium from calcined slag, solid residues containing from 7 to 10% of manganese are formed, which are suitable for extraction. A study of the mineralogical composition of solid residues shows that manganese is found in cakes in …

The extraction of manganese from the tailings slag obtained in the production of refined manganese ferroalloys is studied thermodynamically and experimentally. In such extraction, the slag reacts with metal melts (hot metal, ferromanganese, and ferrosilicomanganese) containing reducing elements (carbon and silicon), with the goal of increasing the overall transfer of manganese …

manganese processing, preparation of the ore for use in various products.. 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 adds important physical properties to the metal.

Steel is an alloy made up of iron with typically a few tenths of a percent of carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant need typically an additional 11% chromium.Because of its high tensile strength and low cost, steel is used in buildings ...

Some laboratory experiments are carried out to investigate the reaction between manganese steel and ladle slag. It is found that as expected when the slag basicity [R = w(CaO)/w(SiO 2)] is sufficiently low, for example, R < 4, the dissolved Al in conventional Al‐killed steel could reduce the SiO 2 component of the slag.In the case of manganese steel grades [w(Mn): 6–20%, w(Al): 0.025% ...

Mild steel. Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things - nails, wire, car bodies, ship building, girders and bridges amongst others.
