Upgrading and dephosphorization of Western Australian iron ore using reduction roasting by adding sodium carbonateDe-qing Zhu1,Tie-jun Chun1,Jian Pan1,Li-ming Lu2,Zhen He11. School of Minerals... microscopy and scanning electron microscopy. It is found that phosphorus exists within limonite in the form of solid solution, which cannot be removed through traditional ways. During reduction roasting......

. Aluminosilicates disperse or symmetrically immerse inside goethite. The existential relation between iron and aluminium in the ore is very complex. Magnetic separation and magnetization roasting-magnetic separation are unable to remove aluminum effectively because they are unable to destroy the isomorphous structure of the ore. However, most of aluminum can be removed by sodium-salt-added roasting......

residue, a corresponding technology to prepare mangano-manganic oxide was adopted as follows: low temperature sulfating roasting tungsten residue, leaching, removal of impurities in leachate, precipitation of manganese and oxidation of manganese hydroxide. The product was analyzed by SEM and XRD. The results of roasting and leaching show that the recovery of Mn is 88.9% after roasting with 150% excess......
Effect of reduction roasting by using bio-char derived from empty fruit bunch on the magnetic properties of Malaysian iron oreNurul A.Yunus1,Mohd H.Ani1,Hamzah M.Salleh1,Rusila Z.A.Rashid1,Tomohiro... of the weak magnetic properties of Malaysian iron ore. In this study, bio-char derived from oil palm empty fruit bunch(EFB) was utilized as an energy source for reduction roasting. Mixtures of Malaysian......
