| 摘 要： | 为了给河南某地白云母矿石的开发利用提供依据，对该矿石进行了选矿试验研究。结果表明，在-0.074 mm占50.20%的磨矿细度下，首先通过高梯度强磁选去除黑云母、磁铁矿、赤褐铁矿和电气石等含铁杂质，然后在pH=3的酸性条件下用十二胺将白云母与石英、长石等分离，最终可获得白云母含量为91%、白云母回收率为70.75%、Fe2O3含量为5.10%的白云母精矿，精矿质量满足橡胶填料的工业要求。

| Abstract: | In order to provide the basis for development and utilization of a certain muscovite in Henan，beneficiation tests of the ore were carried out. The results showed that under grinding fineness of -0.074 mm 50.20%，iron-containing impurities including biotite，magnetite，hematite，limonite and tourmaline were firstly removed by using the high gradient high intensity magnetic separation. Then，under the acidic condition of pH=3，muscovite，quartz and feldspar were separated by using dodecylamine. Finally，muscovite concentrate with muscovite content of 91%，muscovite recovery of 70.75%，Fe2O3 content of 5.10% was obtained，which can meet the requirements of rubber filler in industry. |
