摘　　要：某铁矿为一新发现矿床,矿石储量比较大,矿石中硬石膏的存在对资源利用存在不利影响。为了充分开发利用该铁矿资源,对该铁矿进行了多种选矿方案试验研究,结果表明,采用原矿两段磨矿-2次磁选-浮选脱硫工艺,在较粗的磨矿细度条件下,可以获得铁品位为64.48%,硫含量为0.036%,铁回收率为72.72%的铁精矿,该工艺能够满足工程化生产要求。An iron ore is a new deposit with large reserves,but anhydrite in the ore will take negative impact on resource utilization.In order to fully exploit the ore,we have carried out many programs.The results show that iron concentrate with Fe grade of 64.48%,S grade of 0.036% and Fe recovery of 72.72% can be obtained by using two-stage grinding-two-stage magnetic separation-flotation desulphurization,which can meet the requirements of industrial production.
