Abstract：Abstract：The composite agglomeration process is one of the important ways to deal with lowgrade complex symbiotic ore. The traditional composite agglomeration process is generally a high basicity matrix material with acid green balls. In this experiment, the composite agglomeration treatment with fluxed green balls was used to treat vanadiumtitanium magnetite. The fritting quicklime was finely ground and then added to the vanadium titanomagnetite concentrate to prepare fluxed green balls. The basicity of the pellets was controlled between 06 and 12, and the comprehensive basicity of the sinter was 176. The results show that as the basicity of the fluxed green ball increases, the strength of the green ball increases, the permeability of the mixture layer improves, and the sinter yield increases. After finely grinding the coke powder for sintering and adding vanadiumtitanium magnetite to prepare carboncontaining green balls，the amount of coke powder should be controlled at about 04 mass%. When the green ball basicity is 09, the sintered drum has the highest intensity. The analysis results show that, as the basicity of the fluxed green ball in the sinter increases, the degree of embedding of the pellets in the matrix of the finished sinter is higher, the boundary between the pellets and the matrix gradually narrows, the content of composite calcium ferrite and silicate at the boundary increases, and a small amount of perovskite is generated.
