对某全铁品位仅16.54%的贫磁铁矿进行磁选试验,运用磁选柱进行提铁降杂,取得了良好效果,获得了铁品位为65.15%,回收率为80.35%的铁精矿,提出了一个经济合理、易于操作的全磁选流程。
Magnetic leaching test was carried out on a lean magnetite with only 16.54% of the total iron grade. The magnetic separation column was used to carry out iron reduction and impurity reduction. Good results were obtained. The iron concentrate with the grade of 65.15% and the recovery rate of 80.35% , Put forward a reasonable and easy to operate all magnetic separation process.
