Extraction of Iron values from Red mud - ScienceDirect

1/1/2018· Red mud is an aluminum industry waste generated by Bayer’s process. It contains around 30-50% iron oxide depending upon the quality of bauxite ore used in Bayer’s process Due to its highly caustic-corrosive nature and fine particle size it is considered toxic to

MIOX® Micaceous Iron Oxides

Through a process of drying, grinding, screening and cleaning, the rock, which is also known as hematite, is turned into a soft, grey lustrous material with lamellar particles. It is precisely this lamellar structure and the strict adherence to a given grain size distribution that allows its use as a color pigment, with properties which cannot be achieved by any other type of micaceous iron oxide.
