Experimental Study on Beneficiation of an Oxidized Ore from Daye Iron Mine
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.
