摘要: 采用焙烧-磁选流程处理蒙古某铁矿,在800 ℃的温度下,焙烧20 min,然后将该矿磨至细度为68% -0.074 mm,在磁场强度为96 kA/m的条件下进行磁选,可得铁品位为65.03%、铁回收率为90.49%的铁精矿,为赤、褐铁矿的广泛应用找到了切实可行的方法。

Abstract: The process of roasting-magnetic separation was used to treat a Mongolian refractory iron ore.The ore was roasted for 20 min at a temperature of 800 ℃, ground to 68%-0.074 mm and treated by magnetic separation at a magnetic field intensity of 96 kA/m.As a result, an iron concentrate grading 65.03% at a recovery of 90.49% was obtained.It provides a practical method for a wide application of hematite and siderite ores.

Key words: Hematite and siderite ores, Roasting, Magnetic separation
