Alumina reduction in Rajhara iron ore slimes essentially involves separation of hematite from gibbsite in relatively coarser fraction and from kaolinite in the finer fraction. Selective dispersion flocculation studies on synthetic mixtures clearly indicated that while it was possible to achieve almost perfect separation of hematite from kaolinite using starch and PAMX (modified polyacrylamide ...

Ghose (1997) studied that iron ore type, milling operations associated with primary beneficiation process and amount of water in the effluent determine the characteristics of iron ore slime. Ghose and Sen (2001) concluded that in India iron ore slime contains mostly silica, alumina and iron in the form of oxides. In the present study, the chemical constituents of iron ore slime and its amount ...
