Abstract: This paper studies the pellet making process by mixing Zn-bearing BF gas slime and LD dust. The effects of BF gas slime and LD dust rate, pelletizing time, adding water amount, binder amount, pulverized coal amount on the pellet property are studied. The results show that under the following conditions, BF gas slime and LD dust ratio is 2.5: 1, pelletizing time 20 min, adding water percentage 18 %, bentonite adding quality 1 %, adding quantity of coal 10 %, the compressing strength of moist pellets and dry pellets are 18 N·pellet^-1 and 80.36 N·pellet^-1 respectively. The drop strength of moist pellets is 6.9 times·0.5 m^-1. The quality of pellets meet the process demand of rotary hearth furnace for the strength of pellets.
