Molten salt electrolytic beneficiation of iron oxide
The iron ions are electrolytically reduced to iron at the cathode and deposited as high purity iron on the cathode The oxyanions react with a carbonaceous anode to generate CO and/or CO 2 A beneficiated TiO 2 product is recovered from the molten salt or mixture of molten salts In addition to allowing iron beneficiation, with reduced CO 2 emissions, expected advantages of this approach are mainly to reduce the volume of final waste to be disposed: the urgency of the current situation in Alproducing countries was an incentive to explore new routes in view to limiting the growing amount of red muds disposed Moreover, the alkali content of the red mud is to reduce the NaOH Production of electrolytic iron from red mud in The solid:liquid ratio and amounts of impurities contained in red mud were varied to optimize the faradaic yield and the production rate of electrolytic iron Whereas hematite can be reduced to iron with a current efficiency over 80% for a current density (cd) up to 1000 A/m 2 , the current efficiency with red muds was highest for a cd below 50 A/m 2 and then decreased regularly to 20% at 1000 A/m 2 Production of electrolytic iron from red mud in
