摘要：
Based on the typical process mineralogy method, the chemical composition, mineral composition, size distribution and dissemination characteristics of the micro-fine ilmenite sample were investigated through chemical analysis, XRD,SEM and MLA, and then the sample separation features were analyzed and discussed. The research showed that the valuable element Ti of 67.04% occurs in the form of ilmenite, and the primary gangue minerals are titanaugite, chlorite and feldspar. Particle size below 19 μm reaches 74.33% in the sample, among which the size distribution of each mineral has a significant difference, and the valuable minerals are finer than that of the gangue minerals. The ilmenite liberation degree is 90.43%, which is closely interlocked with titanaugite. The results provide the basis for the high-efficiency recovery of the micro-fine ilmenite. © 2019, Editorial Department of Journal of Northeastern University. All right reserved.
