| Abstract: | The mineralogy and microstructure of the briquette fired at different sintering time, temperature and basicity was investigated by means of an optical microscope for Dabaoshan limonite to clarify the mechanism of limonite sintering. The basicity, sintering temperature and time have been optimized for the formation of the limonite sinter with a needle-shaped CaFeO_3 as bonding phase, thus Providing a theoretical basis for developing the new technology of low temperature sintering of limonite. |
