Red titanium manganese ore was irregular granular, produced in Zunhua, Hebei Maoshan granite, was plate, black, metallic luster, a sense of creamy, streak yellow with light green, opaque, weak magnetic, secondary shell-like fracture. Particle size 0.35-0.5mm, specific gravity 4.58, micro-hardness 410.5. Axial crystal negative, reflective color gray brown, internal reflection brown, double reflex polychromatic weak, polarized light color 45 ° brown. Electron probe analysis results of TiO 2 51.73, MnO 32.15, FeO 14.94, Nb 2 O 5 0.54, Ta 2 O 5 0.25, total 99.63. Mineral crystal chemical formula (Mn_ (0.69), Fe_ (0.32)) _ (1.01) Ti_ (0.99) O_3. The results of X-ray analysis showed that the main strong lines of the powder were 2.76 (1) (104), 1.73 (8) (116), 2.54 (7) (110), 2.24 (5) (113), 1.88 (5) (024) 1.51 (5) (214). Tripartite crystal system, space group C_3 ~ 2i-R3.
