Investigation of carbon-based reductant, low-temperature process for conversion of hematite in red-mud to magnetite
MetadataShow full item record
The research reported in this Thesis was confined to a specific red-mud originating from Jamaican bauxite with an iron-content, reported as Fe2O3, of ~60 m%. In principle, separation (selective recovery) of this iron from the red-mud would yield a residual product in which the minor (‘high-value’) Al- and Ti-bearing constituents would be concentrated. Thus, the objective of this research was to explore such a strategy to effect this outcome. Conversion of ‘hematite’ to ‘magnetite’ and subsequent magnetic-classification to obtain a high-Fe magnetic fraction and a low-Fe non-magnetic fraction was ...
