Summary of Iron Ore Beneficiation Process and

Flotation is one of the commonly used methods to separate fine to particulate weakly magnetic iron ore. There are two principle processes of positive flotation and reverse flotation. The former is suitable for quartz hematite ore without easy-floating gangue, and the latter is suitable for ore with easy-floating gangue, and both have production ...
