Ru Wang, Yuexin Han, Yanjun Li, Yu Shu Zhang

Abstract

Suspension roasting furnace was used as the reactor of magnetic roasting of fine grained siderite, and the N2 was used as the conveying gas. The results show that, the siderite ore be roasted at the conditions of gas velocity is 1.7m/s, and the roasted time is 12.35s, according to magnetic separation can obtained iron concentrate grade is 65.04%, and recovery rate is 93.03%.
