The primary product of the smelting process outlined above is a carbon-saturated ferroalloy containing 76 to 80 percent manganese, 12 to 15 percent iron, up to 7.5 percent carbon, and up to 1.2 percent silicon. It can be produced by two methods. In the first, ores are selected on the basis of their acidity so that, on smelting, 70 to 80 percent ...

To yield an acceptable iron and manganese separation, the optimal magnetic intensity for iron separation was 1000–1200 G and that for manganese 11,000–12,000 G. The XRD patterns for both iron and manganese concentrates in Fig. 8 (E) and (F) show that the main phases in the iron concentrate were Fe 3 O 4 and SiO 2 …
