本文介绍了一种测定气泡—矿粒粘附能垒的新方法。矿样系采用具有不同疏水性的甲基化硅石,硅石棒用于测量脱附力,熔合硅石片用于测量接触角,在相同甲基化条件下制得的石英则用于浮选试验和感应时间测定。结果表明,测得的粘附能垒与浮选速度常数及感应时间的相关性很好。 This paper presents a new method for determining the energy barrier of bubble-particle adhesion. The mineral samples used methylated silica with different hydrophobicity, silica rods used to measure the desorption, fused silica sheets used to measure the contact angle, quartz prepared under the same methylation conditions was used for flotation test and Induction time measurement. The results show that the measured adhesion energy barrier and the flotation velocity constant and the correlation time is very good.
