| 摘 要： | 为降低北方磷矿厂的选矿成本，提高浮选指标，东北大学研制了一种常温磷灰石捕收剂DN-6。为检测DN-6的浮选性能，进行了单矿物浮选试验，并通过Zeta电位检测和傅里叶变换红外光谱分析对该捕收剂在磷灰石表面的作用机理进行了研究。单矿物浮选试验结果表明，在矿浆pH=7.6，矿浆温度28 ℃，DN-6用量为166.7 mg/L的浮选条件下，捕收剂DN-6对磷灰石单矿物的浮选回收率可达97.59%。Zeta电位和傅里叶变换红外光谱分析表明，pH＜4时，DN-6在磷灰石表面发生键合吸附。

| Abstract: | In order to test the performance of DN-6 at normal temperature, a new collector developed by Northeastern University, the flotation test of single mineral was carried out, and the mechanism of the collector on the surface of fluorapatite was studied by Zeta potential detection and Fourier transform infrared spectroscopy. The results of single mineral flotation test showed that under the condition of pulp pH 7.6, temperature 28 ℃, and DN-6 dosage 166.7 mg/L, the flotation recovery of fluoapatite by collector DN-6 can reach 97.59%. Zeta potential and FTIR analysis showed that DN-6 had bonding adsorption on the fluorapatite surface when pH＜4. |
