Abstract: Smelting the pellet of metallic powder ore is one of means in effective utilization of precious metal ore resources. With the new organic and inorganic composite binder made by ourselves, the influences of heat curing systems and binder amount to the force after ferruginous powder ore to be pellets were explored and the adaptability of the process for different ferruginous powder ore was further investigated. The results showed that the process of the first 105℃ heating for 0.5 h, and following heating to 500 ℃ for1 h, made the radial pressure resistance of the pellet samples increase from 1.573 1 kN to 1.912 2 kN. This is resulting from the clay sinter in ore powder. When binder amounted to 12%, the pressure resistance reached 1.912 2 kN and the drum index of pellet tumbler index reached 67%, which met the practical requirements of production. The experiments for different ferruginous powder ore showed that the process does not have special requirement on ore powder material, and can be widely applied.
