采用浮选法对青海某高泥钾矿中的泥（水不溶性矿物）进行了分离研究。以表面活性剂（脂肪酸聚氧乙烯酯）-煤油水乳液为捕收剂，可获得较高的煤泥浮选回收率。为了了解脱泥浮选过程的机理，测试了煤油/水乳液在水中和KCl饱和溶液中的稳定性。结果表明，在较低的表面活性剂浓度下，乳液发生明显的相分离。乳液微观结构的显微镜观察表明，液滴是球形的，与低表面活性剂浓度的样品除外，并且液滴尺寸随着表面活性剂浓度的降低而增加。KCl饱和溶液中的乳状液滴比纯水中的小。此外，由于该乳液在KCl饱和溶液中具有较高的表面活性，因而更容易在KCl中稳定，可用作浮选脱泥的捕收剂。
The removal of slimes (water-insoluble minerals) from high slime-containing potash ores from Qinghai Province, PRC, was investigated using flotation. A higher slime flotation recovery was obtained when a surfactant (polyoxyethylene fatty acid ester)–kerosene water emulsion was used as the collector. The stabilities of the kerosene/aqueous emulsions in water and in KCl saturated solution were tested to understand the mechanism of the desliming flotation process. The results showed that the phase separation of the emulsion was pronounced at low surfactant concentration. Microscopic observation of the emulsion microstructure indicated that the droplets were spherical with the exception of samples with low surfactant concentration and that the droplet size increased with decreasing surfactant concentration. The emulsion droplets in the KCl saturated solution were smaller than those in pure water. Additionally, the emulsion was easier to stabilize in KCl because of the higher surface activity in KCl saturated solution; therefore, this emulsion can be used as a collector in desliming flotation.
