Blue dust washing

Blue dust is a natural occurrence of iron-ore 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. By introducing our Evowash ore processing plant you are able to effectively remove the Alumina and Silica which has the effect of improving the Fe grade. Grade improvements of up to 10% have been achieved through our iron ore processing plant technology.
