选矿包括细粒的处理，细粒不仅受重力的作用，而且也受到长程表面力的作用[2]。颗粒间的相互作用力决定了致密团聚体或絮凝体的形成及破坏、浮选工艺及微粒和超细粒的过滤。表面力的理论和实验研究主要结果是与胶体和膜的稳定性。分散体系的力学性质、多孔材料中质量的传输、润湿和膜的分离相联系的[2]。
Beneficiation involves the treatment of fines, which are not only affected by gravity but also by long-range surface forces [2]. Interactions between particles determine the formation and destruction of dense agglomerates or flocs, flotation processes, and filtration of particulates and ultrafine particles. The main results of theoretical and experimental studies of surface forces are with the stability of colloids and membranes. The mechanical properties of dispersed systems, the transport of mass in porous materials, wetting and membrane separation are linked [2].
