鞍山式赤铁矿预选粗精矿悬浮态磁化焙烧—磁选试验研究
Experimental study on utilization of crude concentrate from an Anshan?type hematite ore by suspension magnetization roasting?magnetic separation
摘要
Abstract
Magnetization roasting via a laboratory-batch scale fluidized reactor was carried out for the utilization of crude concentrate from an Anshan-type hematite ore, whichwas performed at 450?700℃ in mixed H2 and N2 atmosphere. The results show that the gas flow is 8 m3/h, the roasting temperature is 650℃, the hydrogen volume fraction is 40% and the material cycles is 3, and a high grade concentrate containing 65.46% iron with an iron recovery of 88.10% is achieved by magnetic separation with a magnetic field strength of 80 kA/m under above conditions.关键词
