Abstract: In order to solve the problem in development and utilization of Yuanjiacun amphibole type extremely complex iron ore，tests of deep reduction-low intensity magnetic separation process were conducted.The results showed that iron concentrate with iron grade of 91.60% and recovery of 94.35% was obtained under the condition of raw ore size -2.0 mm，coal blending coefficient 1.5，pulverized coal size -2.0 mm，mass ratio between additives CaO and ore+coal 5%，reduction temperature at 1 275 ℃ for reduction time 60 min，grinding reduction products to 80% -0.074 mm，LIMS for one time at magnetic field intensity 127.39 kA/m.The deep reduction-low intensity magnetic separation process provides strong technical support for effective development and utilization of Yuanjiacun amphibole type hematite
