目前,许多研究人员正在着手解决有关脂肪酸盐胶粒生成的临界浓度的控制方面的问题,因为这些问题对浮选过程来说均有很大的实际意义。由于胶粒的吸附活性和浮游活性都相当低,所以在浮选过程中使捕收剂的耗量增多并降低工艺指标。要提高捕收剂的活性,就需要采用不同的方法进行分散。这样才能排除胶粒的凝聚现象并使胶粒溶液部分地变为真溶液。我们知道,根据不同的碳氢化合物原子团的成分、结构和长度,带极性的有机物质能够提高或者降低脂肪酸皂的胶粒生成的临界浓度。在浮选过程中,大量带极性的有机物质可用作起泡剂。我们认为捕收剂与
At present, many researchers are working to solve the problem of controlling the critical concentration of fatty acid salt micelles, because these problems have great practical significance for the flotation process. Due to the relatively low sorption activity and the floating activity of the colloidal particles, the collector consumption is increased during the flotation process and the process indicators are reduced. To improve the collector activity, you need to use different methods for dispersion. In this way, the colloidal aggregation can be eliminated and the colloidal solution partially becomes a true solution. We know that depending on the composition, structure and length of the different hydrocarbon radicals, polar organic substances can increase or decrease the critical concentration of the fatty acid soaps. In the flotation process, a large number of polar organic substances can be used as foaming agent. We think collectors and
