Analysis of the current technical solutions for the processing of iron ores showed that the highgrade ores are directly exposed to metallurgical processing; by comparison, lowgrade ores, depending on the mineralogical and material composition, are directed to beneficiation including gravitational, magnetic, and flotation processes or their combination. Obtaining highquality concentrates ...
