This result suggests that milling process could separate iron oxide cluster from TiO 2 cluster accompanying decreasing Fe–O–Ti linkage or separating the amorphous part by dissolution in acid solution.
The VTM ore obtained from the Gwanin mine contained a very high concentration of iron-bearing minerals (approximately 84% from magnetite and ilmenite mineral phases). In addition, a combination of biotite, which is an iron-based mica group, and hercynite, which is a FeAl 2 O 4 formula spinel mineral, were found to an constitute …
As ilmenite is found in igneous rocks, it is co-abundant with impurities like monazites as accessory mineral. The main constituents of monazites are phosphates, cerium group rare earths and thorium. Due to the weathering of the ore, some of the monazites get liberated from the ilmenite grain and form separate grains (Gupta and …
