To realize quality improvement and desiliconization of high-silicon bauxite, binary and ternary collectors were prepared with sodium oleate as the main component, compounded with benzohydroxamic acid, sodium dodecyl sulfonate, sodium dodecyl sulfate and n-octanol, respectively. The effects of single collector, binary collector and ternary collector on the flotation of high-silicon bauxite were systematically investigated. The interaction mechanisms between diaspore and kaolinite in bauxite and the collectors were revealed via contact angle measurement, zeta potential test, Fourier transform infrared spectroscopy and reagent adsorption capacity analysis. The results indicate that flotation performance of binary collectors is obvious superior to that of single collector. Flotation with sodium oleate combined with benzohydroxamic acid at a total dosage of 800 g/t can produce the concentrate with an Al₂O₃ grade of 56.49% at a recovery of 64.85% and an alumina-to-silica ratio of 2.96. While with a ternary collector composed of sodium oleate, benzohydroxamic acid and sodium dodecyl sulfonate at a total dosage of 1 200 g/t, the flotation can yield the concentrate with an Al₂O₃ grade of 61.17% at a recovery of 79.84% and an alumina-to-silica ratio of 3.80. The contact angle, zeta potential, infrared spectroscopy and adsorption capacity results demonstrate that both the binary collector and the ternary collector interact more strongly with diaspore than with kaolinite, suggesting that the collectors possess better selective collection of diaspore.

为了实现高硅铝土矿的提质脱硅，以油酸钠为主体，分别与苯甲羟肟酸、十二烷基磺酸钠、十二烷基硫酸钠和正辛醇复配成二元、三元组合捕收剂，研究了单一捕收剂、二元组合捕收剂以及三元组合捕收剂对高硅铝土矿浮选效果的影响。通过接触角、Zeta电位、红外光谱和药剂吸附量测试等探究了铝土矿中一水硬铝石和高岭石分别与组合捕收剂的作用机理。结果表明，二元组合捕收剂的浮选效果明显优于单一捕收剂，油酸钠与苯甲羟肟酸组合，总用量800 g/t时，精矿Al₂O₃品位56.49%、回收率64.85%、铝硅比为2.96；油酸钠、苯甲羟肟酸与十二烷基磺酸钠三元组合，总用量1200 g/t时，精矿Al₂O₃品位61.17%、回收率79.84%、铝硅比为3.80。接触角、Zeta电位、红外光谱及药剂吸附量测试结果表明，组合捕收剂对一水硬铝石的作用大于对高岭石的作用，表明组合捕收剂对一水硬铝石有着更强的选择捕收性。
