摘　　要：分析了某长石矿的主要矿物成分,通过试验,首先采用阴离子、阳离子混合捕收剂反浮选工艺除去细粒的含铁矿物,然后采用强磁选工艺除去粗粒的铁矿物和黑云母,制定反浮选-强磁选联合工艺流程,可获得K2O+Na2O含量为13.92%、Fe2O3含量为0.20%的钾长石精矿。The main mineral compositions in a feldspar ore were analyzed.The fine particle minerals containing iron were removed by reverse flotation with a collector of anion and cation in the test.Then,the coarse particle iron ores and biotite were removed by high intensity magnetic separation.Use of the combined process of reverse flotation-high intensity magnetic separation could achieve the potash feldspar concentrate with 13.92% K2O＋Na2O and 0.20% Fe2O3.
