Production of Ferro- Manganese – IspatGuru

Jun 19, 2018· Production of Ferro- Manganese. 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 %.

Zinc smelting - Wikipedia

Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point. At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific measures are taken to prevent it.

Extraction and separation of manganese and iron from ...

The fusibility difference between the manganese silicates slag and molten iron or iron carbides is the key point for the separation of Mn and Fe. The high temperature reduction and smelting separation procedures are conducted in one furnace, such as the blast furnace (BF) or electric arc furnace (EAF).

The Extraction of Iron - Chemistry LibreTexts

The air blown into the bottom of the furnace is heated using the hot waste gases from the top. Heat energy is valuable, and it is important not to waste any. The coke (essentially impure carbon) burns in the blast of hot air to form carbon dioxide - a strongly exothermic reaction. This reaction is the main source of heat in the furnace.
