| 摘 要： | 贵州某硅钙质磷矿中主要目的矿物为氟磷灰石, 主要脉石矿物为石英、白云石以及黏土矿物, 矿物共生关系复杂。为了脱除其中的杂质, 使用捕收剂WF-04和M-51, 采用双反浮选工艺脱除其中的硅、镁杂质以及倍半氧化物, 可得到P2O5品位34.45%、MgO含量0.94%、SiO2含量6.64%、Al2O3含量1.67%、Fe2O3含量0.58%、P2O5回收率79.19%的磷精矿。通过Zeta电位和红外光谱分析研究了脱硅捕收剂M-51的作用机理, 结果表明, M-51通过物理吸附伴随氢键作用有效地吸附在石英表面, 而在磷灰石表面几乎不吸附。

| Abstract: | In a siliceous-calcareous phosphate ore in Guizhou, fluorapatite is the main mineral to be recovered, while quartz, dolomite and clay are the main gangue minerals therein, among which there exists a complicated intergrowth relationship. A double reverse flotation process with collectors of WF-04 and M-51 were adopted to remove the impurities of silicon, magnesium and sesquioxides, leading to a phosphate concentrate grading 34.45% P2O5 at 79.19% recovery, with content of MgO, SiO2, Al2O3 and Fe2O3 therein reduced to 0.94%, 6.64%, 1.67% and 0.58%, respectively. Based on the zeta potential and infrared spectroscopy analyses for the reaction mechanism of M-51, it is found that M-51 can be effectively adsorbed on quartz via physisorption and hydrogen bonding, although it can be hardly adsorbed on apatite. |
