| 1 | 季盐在高岭石(001)面上的吸附动力学模拟显示文摘首次将季盐作为捕收剂用于高岭石浮选研究,通过单矿物浮选试验、动电位测定和分子动力学模拟,分析了十二烷基三甲基氯化铵(DTAC)和十四烷基三丁基氯化(TTPC)对高岭石的浮选行为和作用机理.结果表明,高岭石浮选回收率在98%情况下,TTPC药剂用量仅为DTAC用量的一半.季盐TTPC特有的分子结构促进了其与矿物表面间CH…O氢键的形成;更强的静电作用力和吸附能使得季盐(TTPC)在高岭石表面吸附更加牢固,从而使其具有更优异的浮选性能. | 陈攀 孙伟 岳彤 | 2014 | 中国矿业大学学报2014，43，2： | 13 |
| 2 | 湖北某磷矿反浮选钾长石试验研究显示文摘针对湖北某低品位难选硅钙(镁)质磷矿,主要脉石矿物为钾长石,原矿P2O5品位19.84%,Si O_2品位27.78%。在磨矿细度-0.074 mm占比80.16%,预先脱除白云石及细泥的情况下,用醚胺类捕收剂T-609反浮选钾长石,可获得精矿P2O5品位33.65%,回收率达72.83%的良好指标,实现了磷灰石和钾长石的有效分离。捕收剂T-609与钾长石主要以物理吸附为主,T-609和消泡剂TOP的搭配使用,可有效改善阳离子捕收剂反浮选钾长石泡沫性能。 | 刘鸣 葛英勇 孟雨 朱国庆 | 2018 | 硅酸盐通报2018，37，2： | 9 |
| 3 | Comparative studies on phosphate ore flotation collectors prepared by hogwash oil from different regions显示文摘In order to compare the differences between variations of phosphate ore flotation collectors prepared by hogwash oils, JZQ-F collectors were prepared by the hydrolysis method using four types of hogwash oils from different regions in China. The components of the hogwash oils were determined using Fourier transform infrared spectroscopy(FIIR) spectra analysis, while the components of the JZQ-F were determined through gas chromatography–mass spectrometry(GC–MS). The flotation effects of the JZQ-F collectors were investigated by flotation experiments and the adsorption characteristics were determined through the quartz crystal microbalance(QCM-D). Results show that the JZQ-F collector from the Ordos area has 27.43% unsaturated fatty acids. JZQ-F collectors from Beijing, Qingdao, and Dongguan areas contain over 62% of unsaturated fatty acids, which can acquire phosphorous concentrates with a the grade of P_2O_5 above 31.96% and the recovery higher than 91.52%. These three collectors have a larger adsorption capacity, faster adsorption rate, and stronger adsorption structure on apatite surface, which contributed to a good adsorption performance and a favorable flotation effect. | Yu Huimei Wang Huajun Sun Chuanyao | 2018 | International Journal of Mining Science and Technology2018，28，3： | 5 |
| 4 | Relative floatability as a criterion for evaluating the separation performance of phosphate from iron显示文摘This work was aimed to study the relative floatability of phosphate flotation by means of kinetic analysis.The relative floatability is important to determine how selectively the phosphate is separated from its impurities. The effects of pulp pH, solid content, reagents dosage(depressant, collector and co-collector) and conditioning time were investigated on the ratio of the modified rate constant of phosphate to the modified rate constant of iron(relative floatability). The results showed that a large dosage of depressant associated with a low value of collector resulted in a better relative floatability. Increasing the co-collector dosage, conditioning time and pH increased the relative floatability up to a certain value and thereafter resulted in diminishing the relative floatability. Meanwhile, the results indicated that increment of solid concentration increased the relative floatability in range investigated. It was also found that that maximum relative floatability(16.05) could be obtained in pulp pH, 9.32, solid percentage, 30,depressant dosage, 440 g/t, collector dosage, 560 g/t, co-collector dosage, 84.63 g/t and conditioning time,9.43 min. | Azizi Asghar Seyyed Alizade Ganji Seyyed Mohammad | 2017 | International Journal of Mining Science and Technology2017，27，3： | 1 |
