The Baonang Bayan Obo Iron Ore is a high-temperature hydrothermal replacement ore deposit after the magmatic period with complex mineral composition. The main useful minerals are: magnetite, hemi-illusion hematite, illusion hematite, hematite and limonite and other iron minerals; bastnaesite, monazite and other rare earth minerals; niobite, calcite , Ilmenite and other rare minerals and fluorite. Main gangue minerals are: sodium pyroxene, sodium amphibole, quartz, mica and other silicates; dolomite, calcite and other carbonates; barite, pyrite and other sulfates and sulfides; apatite Phosphates. Mining iron ore between the embedded closely, especially the magnetic
