This paper presents an innovative technology that has been developed for the smelting of Egyptian low-grade manganese ore to produce low-manganese pig iron and high-manganese slag. This produced slag has a high Mn/Fe ratio, which, therefore, can be used in a second smelting process in the production of manganese alloys. In this developed ...
