By Stephen Dietz 07.29.2014. Slag is a by-product of the metallurgical smelting process. Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process in order for the desirable elements to stay in the melt

PART I – FERRO MANGANESE. Slag is a partially vitreous byproduct of metal smelting to separate the metal fraction from the unwanted fraction. Ores often have unwanted minerals associated with them, like silica, and during the process of smelting this can combine with other materials in the furnace and the fuel to produce something that looks a lot like lava.
