The bonding intensity of four kinds of ores from Brazil, Australia and South Africa is researched in this study, and the influence factors are analyzed. The results show that, the ores of different types have apparently differences in bonding intensity, ores from Brazil and South Africa have high bonding intensity, while ores from Australia have low bonding intensity; The foundation of generation of effective liquid is adequate liquid phase fluidity and the lower porosity of core ore; The ratio of porosity of core ore and the index of liquid phase fluidity has negative correlation with the bonding intensity.

State Analysis

The reserve of tin-bearing iron ores is very large in China. However, they have not been utilized sufficiently so far due to the complex embedded relationship between iron- and tin-bearing minerals. In the present work, the behavior of tin in the tin-bearing iron concentrates during a reduction sintering process (RSP) were studied using XRD, SEM-EDS, chemical valence state analysis and morphology analysis. The results show that there is about 30 mass% tin deprived from the tinbearing iron concentrates by the RSP. The tin-bearing phases remained in the finished sinters exist as the form of stannic (Sn4+), stannous (Sn2+) compounds and metallic Sn (Sno). The atmosphere in the sinter bed during the RSP is theoretically suitable for the volatilization of SnO(g). However, the gas composition and temperature of the sintering gas flow are changeable, which bring about adverse effect to the deprivation of tin.

Sintering Processes

The research status of the iron ore’s high temperature behaviors in the sintering process was reviewed in this paper. The influencing factors of the high temperature behaviors and their effects on the sinter performances were discussed, and the prospects of the optimization of ore proportioning based on the iron ores’ basic characteristics were also proposed. It is suggested that the melting behavior and infiltration behavior of the sintering liquid should be further investigated. Moreover, the limiting links of the sinter quality for different iron ores sintering should be analyzed by combining the basic characteristics and the production technology of the industrial sintering processes. Given priority to the low fuel ratio and the sinter quality, the complementary principles of the iron ores basic characteristics and mathematical models should be used in the optimization of ore proportioning.
