Occurrence of Scandium in a Ilmenite Ore in Northwest China

This is an essay in the field of process mineralogy. In order to find out the properties of low-grade titanium ore with scandium, chemical analysis, electron microscope, X-ray diffraction, automatic mineral analyzer and optical microscope are used to analyze the material composition and mineral embedding characteristics of the ore. From the perspective of process mineralogy, the occurrence state of titanium, iron, and scandium has been studied in detail. The results show that the scandium in the ore mainly occurs in calcium-magnesium silicate, with a distribution rate of 94.93%. An excellent scandium recovery index can be obtained by beneficiating and smelting this silicate mineral. The research results have important guiding significance for the selection and smelting of scandium associated with titanium ore and the next development and utilization of the deposit. It also has important implications for the study of the occurrence of scandium in similar scandium-bearing titanium deposits.
