Abstract: The chemical composition, phase composition, occurrence state of element, dissemination relationship and size distribution of the paigeite ore were analyzed by optical microscope, chemical analysis, XRD and SEM analysis. The results show that mineral composition of the paigeite ore is very complex. Main boron minerals are szaibelyite and paigeite, boron content in szaibelyite accounting for 89.01% of total boron content. Main iron mineral is magnetite, iron content in magnetite being 85.60% of the total iron content. Serpentine is the main gangue mineral. The dissemination relationship among szaibelyite, magnetite and serpentine is complex, and dissemination particle size distribution of different minerals is uneven. Dissemination particle sizes of szaibelyite, magnetite and serpentine are coarser, while that of paigeite is fine.

Key words: paigeite, mineralogy, mineral composition, dissemination characteristic, particle size distribution
