In a medium-grade siliceous-calcareous phosphate ore from the Yichang region of Hubei Province, the fluorapatite is the target mineral and potash feldspar, dolomite, and quartz are the main gangue minerals, and the P₂O₅ grade of the raw ore is 23.27%. To enhance its utilization efficiency of the ore, a double reverse flotation process was adopted, and systematic optimization tests were conducted on grinding fineness, dosages of collectors (H-1, KM-6), and auxiliary reagents (phosphoric acid, HF-959). The flotation mechanism was revealed through measurements of contact angle, Zeta potential, and infrared spectroscopy. The results show that under the grinding fineness of 75 μm accounting for 81%, a closed-circuit flotation flowsheet consisting of one roughing and two sweeping for desilication followed by one roughing and one sweeping for demineralization, a high-quality phosphate concentrate with P₂O₅ grade of 32.20% and recovery rate of 81.20% can be obtained. The Al₂O₃ and MgO contents in the concentrate are reduced to 2.02% (a decrease of 53.35%) and 0.62% (a decrease of 60.26%), respectively, effectively achieving the separation of apatite from potash feldspar, dolomite, and other gangue minerals. Research indicates that the collector H-1 primarily adsorbs physically on the surface of potash feldspar, selectively enhancing its hydrophobicity, which is the core mechanism for the efficient removal of potash feldspar.

湖北宜昌地区某中品位硅钙质磷矿石以氟磷灰石为目的矿物，钾长石、白云石和石英为主要脉石矿物，原矿P₂O₅品位23.27%。为了提升该矿石的资源利用率，采用双反浮选工艺，系统开展了磨矿细度、捕收剂（H-1, KM-6）及辅助药剂（磷酸、HF-959）用量优化试验，结合接触角、Zeta电位与红外光谱测试揭示了浮选作用机理。结果表明：当磨矿细度-75 μm占比81%时，采用脱硅一粗两扫、脱镁一粗一扫的闭路浮选流程，可获得P₂O₅品位32.20%、回收率81.20%的优质磷精矿，精矿中Al₂O₃和MgO含量分别降至2.02%（降幅为53.35%）和0.62%（降幅为60.26%），实现了磷灰石与钾长石、白云石等脉石矿物的分离。研究表明，捕收剂H-1以物理吸附为主，选择性作用于钾长石表面，显著增强其疏水性，是实现钾长石高效脱除的核心机制。
