Analysis of Supporting Technology and Facilities of Suspension Magnetization Roasting Technology in Jiusteel
Suspension magnetization roasting-low intensity magnetic separation is a new process for the treatment of Jingties-han type refractory iron ore in the concentrator of Jiusteel Group.The process was applied to the concentrator in 2018,and a good indicator of iron concentrate grade of 55%and recovery rate of 86%was obtained.However,due to the instability of the supporting system of the suspension furnace,such as the grinding particle size,concentrate moisture after filtration,and easy blockage of pump and pipeline transportation,the normal production of the suspension furnace is affected.This paper mainly discusses the influence of the equipment of the supporting process of suspension furnace pre-screening,grinding classification,magnetic separation,flotation and filtration system on the feeding of suspended furnace.
