Removal of fine gangue minerals from Chador-malu iron ...

Phosphorus and silica are the main impurities of the Chador-malu iron ore which need to be reduced to the required values of 0.1 and 2%, respectively. The impurities in the final iron concentrate are mainly due to the presence of fine particles (less than 25 μm) of silica and apatite in the concentrates of magnetic separators and flotation circuits. In this study, the removal of very fine ...
