Ferro Manganese
This is a type of ferro alloy with a high content of manganese. Made by heating mixture of mno2 and fe2o3 oxides with carbon in a furnace. These undergo thorough thermal decomposition reaction and are used as steel deoxidizer. Nouvelle Gabon plans to produce the following grades of ferro manganese from its 4 x 21 smelter project once it is commissioned.
