Production and characterization of nano-magnetic material through different red mud reduction processes

Red mud valorization by thermal reductive treatments with carbon-rich ashes or under Hydrogen flow. • RM pre-treated by oxidative thermal procedure or acid washing to increase magnetic iron phases quantity in the obtained powders. • Characterization of the new produced materials under chemical and physical point of view for its use. • Magnetic behaviour of the proposed material and potential use to close the red mud life cycle.
