用二辛基二甲基溴化铵(BDDA)对白钨矿和方解石的可浮性进行了研究。在微浮选槽中对单一矿物和混合矿物进行了pH值对浮选效果的影响实验。并对油酸进行了测试以进行比较。结果表明,BDDA的浮选性能优于油酸,且在pH值为8 ~ 10的范围内,BDDA的浮选效果最好。通过初步分析,认为BDDA与白钨矿的反应是通过静电作用进行的。
The flotability of scheelite and calcite was studied with Dioctyl dimethyl ammonium bromide (BDDA). The experiments were conducted on individual and mixed minerals as a function of pH with a micro-flotation cell. And oleic acid was tested for comparison. The flotation results revealed that the performance of BDDA is better than that of oleic acid and the best separation could be achieved with BDDA over the pH range 8–10. Through preliminary analysis, it is concluded that BDDA reacts with scheelite through electrostatic interaction.
