· Manganese, which is intentionally present in nearly all steels, is used as a steel desulphurizer and deoxidizer. It improves the tensile strength, workability, toughness, hardness and resistance to abrasion. By removing sulphur from steel, manganese prevents the steel from becoming brittle during the hot rolling process. Silico manganese
Manganese it´s an essential component of steelmaking process because it improves certain properties that steel by itself doesn´t have. To name a few, manganese allows to avoid a phenomenon called "hot shortness", which causes a surface cracking process at high temperatures, it has an important ability to combine with Sulphur (an unwanted element in .
Answer (1 of 3): When I was an apprentice we used sheaves made of cast steel with a high manganese content. They were very tough, and also full of holes left by bubbles in the crude sandcast methods used by foundries at the time, the late 1970s. Machining them was very difficult. The only tool ...
Manganese is mainly used in metallurgical processes, as a deoxidizing and desulfurizing additive and as an alloying constituent. It is also used in the production of drycell batteries, in chemical manufacturing, in the manufacture of glass, in the leather and textile industries, and as a .
The manganese ferroalloys industry in southern Africa permanganate (KMnO4), which was produced for the first time by Johann Glauber in 1659 (Clegg, 2013). Manganese dioxide (MnO2) was used in the manufacture of chlorine in the mid18th century (Encyclopædia Britannica, 2013).
Manganese. Steels usually contain at least % manganese because it assists in the deoxidation of the steel, prevents the formation of iron sulfide and inclusions, and promotes greater strength by increasing the hardenability of the steel. Amounts of up to % can be found in some carbon steels. Chromium
manganese as an additive in the steel making process. How stainless steel is made material, manufacture, Stainless steel is an ironcontaining alloy—a substance made up of two or more chemical elements—used in a wide range of as an additive in the steel making process,Optimisation of Ferro Alloy Usage in Steelmaking in this paper includes all .
Silicon Manganese alloy in the steel has a strong deoxidation capacity, With a high content of Si and Mn alternative silicon calcium barium, silicon aluminum barium to change the distribution of impurities in the liquid steel form, Refine the grain, improve the processing performance of steel, play an important role to improve steel quality.
· FeMn is an important additive used as a deoxidizer in the production of steel. It is a master alloy of Fe and Mn with a minimum Mn content of 65 %, and maximum Mn content of 95 %. There are two families of Mn alloys. One is called FeMn while the other is known as silicomanganese (SiMn).

The use of manganese in steel production is a doubleedged sword, as the metals fortune is intimately tied to the steel industry. Whenever there is a severe downturn in steelmaking manganese also suffers [5] . Hence, the need to develop a simple and practicable route for the processing and extraction of manganese from its ores is necessary.
