Ore Melting and Reduction in Silicomanganese Production
The charge for silicomangansese production consists of manganese ore (often mixed with ferromanganese slag) dolomite or calcite, quartz, and in some cases, other additions. These materials have different melting properties, which have a strong effect on reduction and smelting reactions in the production of a silicomanganese alloy. …
Production of Ferroalloys
Medium-carbon ferromanganese contains 1–1.5% carbon and has a manganese content of 75–85%. Medium-carbon ferromanganese can be produced either by refining high-carbon ferromanganese with oxygen or by the silicothermic route, whereby the silicon in silicomanganese is used to reduce additional MnO added as ore or slag.

ferromanganese, all you need to know about it
High carbon ferromanganese (HCFeMn) is an alloy composed primarily of manganese (around 70-80%), carbon (6-8%), and silicon (1-2%). It is a type of ferroalloy, which is an alloy of iron and one or more other elements, used in the production of steel and other alloys. The primary use of high carbon ferromanganese is in the production of steel.
Geographic and Oceanographic Influences on Ferromanganese Crust
Ferromanganese (FeMn) crusts are chemical sedimentary rocks composed predominantly of iron and manganese oxide minerals. These deposits grow on the flanks and summits of seamounts and other midplate volcanic edifices throughout the global ocean. They are a hydrogenetic mineral deposit, forming by the precipitation of iron and …
