高梯度强磁选回收菱铁矿试验

Research on the Recovery of Siderite by High Gradient Magnetic Separation

某菱铁矿石含铁33.64%,采用1粗1精高梯度强磁选工艺回收,可获得铁品位为40.02%、铁回收率为94.79%的铁精矿。菱铁矿选别效果较好,可为同类资源的开发提供参考。

A siderite ore contains 33.64% Fe. By high gradient high intensity magnetic separation technology consisting of one stage rougher and one stage cleaner, good separation index can be achieved, the iron concentrate contains 40.02% Fe, the recovery of iron is 94.79%. The separation effect of the siderite is good enough to provide technology guidance to the iron resources development of the same type.
