In order to make better use of Brazilian coarse concentrate as raw material for pelletizing, the grindability, grinding conditions and pelletizing index of Brazilian coarse concentrate are studied. The results show that Brazil coarse concentrate is easy to be ground, using MQY4385 wet overflow ball mill, the mill utilization factor q_-0.074mm = 1.03 t/(m3·h). When the feeding capacity is 70.00~100.00 t/h, and the mass fraction of grinding ore is 52.46%~58.49%, all mass fractions of -0.074 mm of grinding products are greater than 75% with good spheroidization. After the pre-grinding of Brazilian coarse concentrate, the balling is made separately, and a better green pellet index can be obtained. The falling strength of the pellets produced by Daye iron ore concentrate with 20% Brazilian crude filtered concentrate is 3.7 times/(0.5 m), the compressive strength is 11.05 N/P, and the moisture of the green pellets is 6.62%, which improved the green pellets index of Daye iron ore concentrate when pelletizing alone.
