If silico manganese slag is used less fuel is required to be burned resulting in reduced emissions and a saving in carbon taxes. The other is the C0 2 removed from limestone. As part of the C0 2 producing limestone has been replaced with precalcined silico manganese less C0 2 is produced here as well offering a further reduction in Carbon ...
Silicomanganese with 2830 percent Si, for which pecially prepared highmanganese lowphosphorous slag serves as raw material, is used in the production of metallic manganese. The standard grade silicomanganese contains 14 to 16% of silicon, 65 to 68% of manganese and 2% of carbon. The low carbon grade SiMn has carbon levels from to %.
Hydrometallurgical Processing of Manganese Ores: A Review. Silicomanganese with 10–26 percent Si (the remainder is Mn, Fe, and impurities) is obtained from manganese ore, manganese slag, and quartzite and is used as a deoxidizer and alloying additive in the smelting of steel, as well as in the smelting of ferromanganese with reduced carbon content by the silicothermic process.
the relative amounts of manganese ores and HCFeMn slag in the raw material mix. A process temperature of 1600 to 1650°C is necessary to obtain metal with sufficiently high content of Si and discard slag with low MnO. FeMn slag has a relatively low melting temperature (about 1250°C) compared with Mnores. Accordingly, a high share of FeMn slag ...

Silico manganese is an alloy with 60% to 68% manganese, 14% to 21% silicon, and 5% to % carbon. It is produced by smelting of slag from highcarbon Ferro Manganese or of Manganese ore with coke and a quartz flux in a submerged electric arc process requires power consumption of about 3, 800 to 4, 800
Merete Tangstad, in Handbook of Ferroalloys, 2013. PostTap Hole Processing for FeMn and SiMn. Both ferromanganese and silicomanganese furnaces are tapped every 2 to 3 hours. Even for duplex practice, there is a substantial amount of slag (Tables and ), so especially in the case of larger furnaces there are often separate tap holes for slag and metal.
Silicothermic route – In the silicothermic route for the production of medium C FeMn, a high grade slag or a melt containing Mn ore and lime (CaO) is contacted with SiMn containing Si in the range of 16 % to 30 %. The Si in the alloy acts as the reducing agent in the process, which reduces the Mn oxide in the melt according to reaction Si ...
