From the fields of regional crust-mantle structure, metallogentic settings, history of tectonic-magmatic activity, distribution of high antimony anomaly, characteristics of deposit, origin of ore-forming materials (including Sb, C, Si, S, solution and associated elements), black dikes, the relation of deposit and mantle metasomatism fluid is expounded by means of geology and geophysics. Xikuangshan antimony deposit is proved to be a typical vein deposit formed by mantle metasomatism fluid. On the basis of this knowledge, the prospecting criteria of blind orebody of the deposit are given as follows: extensive structuer which indicating the activities of mantle metasomatism fluid, change of host rocks (especially exsisting shale barrier bed), silication and carbonization alteration.

Synthesized all above, the heat and mass transfer of charge bed is discussed in detail. After choosing seriously the former study results in this field, a whole temperature range process model for firing iron ore pellets containing solid fuel is established as well as its software is edited. The main physical chemistry reaction process within pellets and the heat statement can be calculated exactly with the process as long as the physical and chemical parameters of raw material are obtained through basic experiments. After finding out the reason of"temperature hysteresis"and"heat inertia"of the experimental induration device, a new kind of experimental induration device is designed. The"temperature hysteresis"of hot gas flow in the new device is avoided.

In the experiment of fluid bed, when the iron ore has been reduced for 120 minutes with the use of CO·CO〓·H〓 mixture containing 20%CO〓 at the temperature of 700℃, the reductivity and metallization can both exceed 90%, and the rate of iron carbide exceeds 73%.

The traditional technology of iron carbide production exists the problem that the reaction time is too long. The research of adding the additive into the ore of the fluid-bed was carried out in order to find the catalyst of this reaction. It was found out that K2CO3 and CaCl2 can be the catalysts of this reaction. The reacting time and equilibrium data in addition of K2CO3 and CaCl2 were examined and were campared with the contrastive experimental results respectively. The theoretical dynamics analysis also reveals that both K2CO3 and CaCl2 can accelerate the iron carbide forming reaction.
