摘要：

表面粗糙度对高效浮选起着至关重要的作用。通过与理想固体表面的对比，本文着重综述了表面粗糙度对气泡在固体表面润湿行为和动态粘附/脱附行为的影响机理。目前关于理想条件下气泡-颗粒间相互作用的动力学研究与实际浮选矿物仍存在一定的差距。此外，结合浮选捕收剂、纳米气泡和润湿状态，详细讨论并总结了表面粗糙度对实际矿物浮选效果的影响。结果表明，在理想条件下建立的相关模型很难或者仅能部分应用于表征实际的矿物浮选过程。未来的研究方向应当注重如何实现通过表面粗糙度调控强化实际矿物颗粒的浮选回收率，例如开发实际矿物颗粒表面粗糙度的量化测定技术，或者将理想情况下气泡-颗粒作用动力学模型与实际矿物浮选过程有机结合起来。
