In order to make better use of low-cost boro-magnesium ore resources and improve the stability of supplying the sintering raw materials，some ore blending samples for the sintering performance of boron magnesium concentrate powder are studied. The results show that，under the existing sintering raw materials and processes，when the mass fraction of boron magnesium concentrate powder is increased from 4% to 8% ，it is helpful to improving the air permeability of the sintering process，the low-temperature reduction pulverization index ( ＞ 3. 15 mm) of sintered ore shows a downward trend，the reducing property increases slightly，the drum strength decreases，the sinter particle size shows a downward trend too，and the soft melt dripping performance of the comprehensive charge deteriorates. When the mass fraction of boron magnesium concentrate powder is ≤6% ，it can meet the requirements of blast furnace production index. After adding 6% boron magnesium concentrate powder，the industrial application results show that，the overall negative pressure of sintering decreases and keeps relatively stable，the strength of the sinter drum decreases; while，from the perspective of metallurgical performance index，the reducibility increases slightly after adding boron magnesium concentrate powder，and the lowtemperature reduction pulverization index( ＞ 3. 15 mm) decreases from 74. 19% to 69. 28% . After this sintered ore is used for blast furnace production，the air volume does not change much，the pressure difference increases slightly and the other indicators of the blast furnace remains well. The following continuous allocation can be used as a means to reduce costs and increase efficiency.
