采用烧结中断法及烧结矿的矿相组成、显微结构检测法,从宏观及微观两方面,研究了稀土在烧结过程中的成矿行为,稀土在烧结矿中主要形成铈钙硅石,当烧结矿中的稀土含量增加时,形成另一种新的稀土矿物。有部分稀土进入到铁酸钙中,少量稀土进入到赤铁矿、玻璃质中,微量稀土进入到磁铁矿中。 Using the method of sinter interruption and the phase composition of sinter and the microstructure detection method, the metallogenic behavior of rare earth during sintering was studied both macroscopically and microscopically. In the sinter, the rare earth mainly consisted of cerite and silica, Rare earth content in the mine increases, forming another new rare earth minerals. Some rare earth into the calcium ferrite, a small amount of rare earth into the hematite, glassy, ​​rare earth into the magnetite.
