摘要
某氧化矿选矿厂为充分利用富余产能,提高铁精矿年产量,对氧化矿进行了选矿试验研究.研究结果表明:采用磨矿—弱磁—1粗1扫强磁工艺流程,在磨矿细度-0.074 mm60%、弱磁选磁感应强度0.14 T、强磁粗选磁感应强度0.9 T、强磁扫选磁感应强度1.3 T的条件下,可获得铁品位64.67%、铁回收率95.16%的铁精矿,产品指标良好,该研究结果为该矿提高铁精矿年产量提供了可行的技术途径,对其他同类矿山具有一定的参考价值.
Abstract
In order to make full use of the surplus capacity and increase the annual output of iron con-centrate,a beneficiation test was carried out on the oxidized ore in an oxidized ore dressing plant.The results show that the grinding-low intensity magnetic separation-one roughing one scavenging high intensity mag-netic separation process is adopted,under the conditions of grinding fineness of-0.074 mm 60%,low inten-sity magnetic separation magnetic field strength of 0.14 T,high intensity magnetic roughing magnetic field strength of 0.9 T and high intensity magnetic scavenging magnetic field strength of 1.3 T,the iron concen-trate with iron grade of 64.67%and iron recovery of 95.16%can be obtained,and the product index is good.The research results provide a feasible technical way for the mine to increase the annual output of iron con-centrate,and have certain reference value for other similar mines.
