Blue dust washing Blue dust is a natural occurrence of ironore in very fine form and is normally of high grade In many instances there are also low grades of such material available in the mines which have a high level of Alumina Silica present However this Alumina and Silica is usually liberated from the iron ore in blue dust reserves
