摘　　要：为了给柏泉铁矿现场磷、铁回收工艺优化提供数据基础,对该含磷铁矿进行了系列可选性试验研究。结果表明:适宜的一段、二段磨矿细度-0.074mm含量分别为40%和85%,进行两段磨矿和三段弱磁选可获得TFe品位64.25%、回收率50.47%、P2O5含量仅为0.03%的铁精矿;选铁总尾矿在捕收剂用量600g/t、水玻璃用量400g/t的条件下,进行1粗3精2扫闭路浮选,可获得P2O5品位30.74%、回收率72.94%的磷精矿。本研究为选厂工艺参数优化提供了数据支持和技术指导。In order to provide the data basis for the optimization of the phosphorite and iron ore beneficiation process in Baiquan,a series of ore-dressing studies were conducted on the phosphorus-containing iron ore.The test results show that the appropriate first and second stage grind fineness for the content of-0.074 mm is 40%and 85%respectively;an iron concentrate just containing 0.03%P 2O 5 with 64.25%TFe grade and 50.47%TFe recovery could be obtained by the two-stage grinding and three-stage weak magnetic separation process;using closed-circuit flotation of one roughing-three cleaning-two scavenging to treat with the total tailings of the magnetic separation under the rougher dosages of 600 g/t collector and 400 g/t water glass,a phosphorus concentrate with P 2O 5 grade of 30.74%and recovery of 72.94%could be obtained.This study provided data support and technological guidance for the process optimization of the Baiquan iron plant.
