在第一部分已显示出了低品位磷矿石对阴离子浮选的反应。在这第二部分是研究用胺盐浮选同样磷矿石,或用阴离子药剂从脱泥矿石所得精矿中选出石英。 由于阳离子捕收剂价格昂贵,因此用它来选别硅质磷酸盐矿石中的硅石并不普遍,但阳离子捕收剂具有许多优点,即有敏锐的浮选选择性,可应用于较粗的给料,以及在大的PH范围内亦能有良好的作用。通常采用的捕收剂是长链的烷基胺和胺皂类,以及聚乙烯聚酰胺和脂肪酸类和(或)脂肪油类的反应产品。 其试验的一般过程与第一部分相同。结果与讨论
In the first section, the reaction of low grade phosphate rocks to anionic flotation has been shown. In the second part of the study, the same phosphate rock was flotated with amine salts, or quartz was selected from concentrates derived from desliming ores using anionic agents. Because cation collectors are expensive, it is not uncommon to use them to select silica from siliceous phosphate ores, but cationic collectors have many advantages, namely, their pronounced flotation selectivity and their ability to be used in coarser Feeding, as well as in the large PH range can also have a good effect. The customary collectors are long chain alkylamines and amine soaps, as well as the reaction products of polyethylene polyamides with fatty acids and / or fatty oils. The general process of the test and the first part of the same. Results and discussion
