The difficulty of mineral separation sharply increases as the particle size of the processed minerals decreases. Similarly, subsequent stages of solid-liquid separation also suffer as the sizes of the treated particles decrease. As a result, separation and recycling of water from fine mineral particles remains a major problem in such fine particle systems. As presently-mined ores often require ultra-fine grinding for efficient separation, it appears that the industry will have to develop new approaches to deal with the increasing amounts of fine particles.

随着被处理矿物粒度的减小，矿物分离的难度急剧增加。类似地，固-液分离的后续阶段也随着处理的颗粒的尺寸减小而受到影响。因此，水与细矿物颗粒的分离和再循环仍然是这种细颗粒系统中的主要问题。由于目前开采的矿石通常需要超细粉碎以实现有效分离，因此该行业似乎必须开发新的方法来处理越来越多的细颗粒。
