Kurzfassung:
In this paper, the tailings produced by non-ferrous metallurgy were magnetically separated to obtain magnetic separation tailings. The sintering performance of magnetic separation tailings was studied by sintering cup experiment platform. In the research process, the differences in
sintering process of different magnetic separation tailings were compared, including vertical sintering speed, sintering coefficient, drum strength, finished product rate, end point temperature and other sintering indexes. At the same time, the obtained sinter was subjected to chemical analysis to obtain its specific components. The influence of magnetic separation tailings with different contents on sintering was obtained by ore blending. The experimental results showed that the copper tailings are not sintered and the yield is only 0%. Tin tailings are not sintered and the yield
is only 22.30%. The aluminum tailings can be s intered into lumps with a yield of only 57.10%. As the proportion of magnetic separation tailings increases, the vertical sintering speed decreases, the sintering utilization coefficient decreases, the sinter drum index decreases, the yield decreases,
the sinter grade decreases, and the SiO 2 , S and P contents increase. In actual production, the proportion of magnetic separation tailings should be controlled below 10%.
