| Abstract: | The process and mechanism of chloridizing roasting of kaolinite containing coal have been investigated with a tubing furnace The main control parameters are the rising rate of temperature, the fixed roasting temperature and time, the environment in the furnace, etc The mechanism is the iron minerals react with chlorinates in the form of FeO and the chlorinates are drained away from the tubing furnace after escaping from the kaolinite |
