In the pH range of 6~12, the results of the flotation tests indicate that the performance of the new combined cationic collector (CS3:CS1=3) and (CS3:CS2=2) is similar, and they are effective collectors for reverse flotation of the iron ores. The combined cationic collectors exhibited the same collectability as dodecylamine, but better selectivity than dodecylamine. By using the combined collector, the dosage of the collector decreased from 1 10-4mol/L to 1 x 10-5mol/L .

单矿物可浮性试验结果表明，在pH=6～12的范围内，新型组合药剂CS_3：CS_1=3和CS_3：CS_2=2具有相近的药剂性能，在其捕收能力与十二胺相当的前提下，不但选择性较十二胺好，而且还能显著提高药剂的协同效应，使药量从单用时的1×10~(-4)4mol／L降至1×10~(-5)mol／L，是铁矿石反浮选的高效捕收剂。

The IR spectra of wastewater simulated with two typical fatty amine flotation collectors of decyl propyl ether amine and stearylamine were studied and the mechanism of degradation of fatty amine flotation collectors by the UV/H2O2/air oxidation method was discussed.

测定了十二烷基丙基醚胺和十八胺两种典型脂肪胺浮选捕收剂模拟废水降解前后的红外吸收谱图，初步探讨了UV/H2O2/air光化学氧化法处理脂肪胺浮选捕收剂模拟废水的降解机理。

Cation group has the capability of charge neutrality and this would make oily wastewater demulsify and remove oil easily. Hydrophobic group would improve hydrophobic-oleophilic nature of the oil granule. Simultaneously, wetting reversed agent would change wetting performance of oil granule, enhance conglutination capability between air bubble and oil granule. And Frother would form bigger foam layer on the water, so it could prevnt granule with air bubble from rolling downward.Using the hydrophobic polymeric flocculant as one of ingredients for flotation agent formula, the flotation agent has good treatment effect.

浮选剂配方中的疏水性高分子絮凝剂分子链上带有的阳离子基团起到电中和作用，使含油污水易于破乳除油，而疏水基团能增强颗粒的疏水性能；润湿反转剂能改变颗粒的润湿性，增强气泡与颗粒的粘附能力；起泡剂在水面能形成强度较大的泡沫层，起阻止带气絮粒向下翻动的作用。

OPF technology had two main points: one was adjusting and controlling traditional flotation operation factors including pulp pH, type and dosage of collector, flotation time and flow structure etc.; The other was not exerting outside electric field and not adding redox reagents to control electropotential.

这种利用矿浆中固有的电化学行为引起的电位变化，通过调节传统浮选操作因素达到电位调控并改善浮选过程的工艺，我们称之为&原生电位浮选(Originpotential Flotation，OPF)&，以区别于采用外加电极或使用氧化—还原药剂调控电位的电位调控浮选(E1ectropotential Control Flotation，EPCF)技术。

Synergistic Compatibility and Effect and Profit. A new-type and high-efficiency frother had been developed which is now used in the column flotation of MICROCEL flotation column at CaiLi Washery.

根据煤炭浮选的特点，借鉴中医药物配伍理论提出了煤炭浮选起泡剂的复配原则，阐述了煤炭浮选药剂复配的必要性和可行性，最后开发出了适用于MICROCEL大型浮选柱的新型高效低廉的起泡剂JF〓。
