摘　　要：硫铁矿制备硫酸过程中产生大量硫酸渣,其中含30%~50%的铁矿物。研究了采用弱磁选、重选等方法回收硫酸渣中的铁矿物。试验结果表明：采用阶段磨矿—重选—磁选联合流程,可以获得铁品位59.61%的铁精矿,产率46.95%,回收率72.79%。Iron mineral of 30%~50% is encompassed in pyrite cinder in process of vitriol production.The comprehensive ore dressing methods including low-intensity magnetic seperation and gravity separation are researched.The results show that by the joint process,iron concentrate which iron grade is of 59.61% can be acquired.Productivity and recovery of iron concentrate is of 46.95% and 72.79%,respectively.
