The mineral processing industry relies on a range of physicochemical methods to separate fine mineral particles from aqueous suspensions. Froth flotation, selective aggregation, selective flocculation are examples of such technologies. It is recognized that the selectivity of these processes strongly depends on modification of the surface properties of the minerals to be so treated. Wettability by water, surface charging, dispersion, and aggregation of the particles can be controlled and manipulated by the addition of dedicated chemicals. In many cases, various types of polymers can be used to perform those specialized tasks.

选矿工业依靠一系列物理化学方法将细小的矿物颗粒从水悬浮液中分离出来。泡沫浮选、选择性凝聚、选择性絮凝都是这些技术的例子。人们认识到，这些过程的选择性在很大程度上取决于要进行这种处理的矿物表面性质的改变。水的润湿性、表面电荷、颗粒的分散和聚集可以通过添加专用化学品来控制和操纵。在许多情况下，可以使用各种类型的聚合物来执行这些专门的任务。
