The Mn / Fe ratio is crucial in producing the commercial ferromanganese grade in a submerged electric furnace. Huge amounts of low-grade manganese ores are located in many countries around the world. These deposits are only partially used in ferromanganese production. The ores contain large quantities of iron and thus the Mn / Fe ratio is low, 3 - 4.

03.07.2019· As with iron, the magnetic properties of these elements depends on their crystal structure and whether the metal is below its Curie point. α-iron, cobalt, and nickel are ferromagnetic, while γ-iron, manganese, and chromium are antiferromagnetic. Lithium gas is magnetic when cooled below 1 kelvin.
