iron ore fines and blue dust processing

Banded Iron Formation to Blue Dust: mineralogical and ...

Jul 18, 2013  In the second stage, the supergene processes upgrade the hydrous iron oxides to fine grain microplaty haematite. The supergene process causes the leaching of remnant silica from hydrothermally upgraded iron ore under a suitable Eh and pH condition and leads to the formation of Blue Dust.
