Based on mineral composition, low-grade iron ores of the Kryvyi Rih basin (Ukraine) can be divided into magnetite and hematite quartzites. Magnetite (Fe 3 O 4) is strongly magnetic and can be easily removed by magnetic separation.On the contrary, hematite (α-Fe 2 O 3) is a weakly magnetic mineral and is hardly attracted by a magnetic field.Hematite quartzite …
