An iron ore contains specularite and hematite which are its main iron minerals. And its main gangue minerals are specularite, part of the clay material and a small amount of quartz. Tests are made on the ore by adopting processes including gravity separation, high magnetic separation, HIMS-gravity separation and HIMS-reverse flotation. The test results show that the separation process of HIMS-reverse flotation can obtain an iron concentrate grading about 66. 62% at a recovery of 58. 38% from an iron ore assaying around 35.00% iron, rather good metallurgical performances.%某地镜铁矿石中主要铁矿物为镜铁矿和赤铁矿,脉石矿物主要为方解石、部分泥质物质和少量石英.采用重选、强磁选、强磁-重选及强磁-反浮选等联合工艺,对该矿石进行了分选试验.结果表明,对这种类型的镜铁矿,采用强磁-反浮选工艺,在原矿铁品位为35.00％的情况下,可获得铁精矿品位66.62％、回收率58.38％的良好技术指标.
