Aluminum Mineral Processing and Metallurgy: Iron
Know More

The heterogeneous minerals in iron-rich bauxite are treated with conventional techniques, such as gravity concentration , magnetic separation , flotation , roasting followed by magnetic separation [21, 22] and chemical leaching [23, 24] All of these conventional techniques cannot recover iron and aluminum from iron-rich bauxite effectively...

Bauxite Enrichment by Microwave
Know More

Magnetising roasting of the bauxite sample was conducted with 20-40% sawdust at temperatures between 870oC and 880oC After magnetic separation, the major phase in the magnetic fraction was magnetite, while gibbsite and boehmite were the major phases in the non-magnetic fraction...
