Understanding mineral-chemical interactions at the solid-liquid interface is an aim for all scientists and engineers that focus on mineral flotation, a process of mineral beneficiation. This article highlights some recent results and publications that have made use of advanced tools of physical chemistry, materials science, and colloid/interface chemistry, to gain insight into the properties of the solid-liquid interface of relevance for one of the most dominant processing techniques used in the mining industry. The focus is entirely on methods of interfacial characterisation that can probe the adsorption of flotation chemicals (termed reagents), and the effect of that adsorption, while the system is immersed in solution, thus maximising the relevance of the studies to a complex aqueous colloidal system. Both theoretical and experimental methodologies are addressed.

了解固液界面上的矿物化学相互作用是所有专注于矿物浮选（矿物选矿过程）的科学家和工程师的目标。本文重点介绍一些利用物理化学，材料等先进工具的最新成果和出版物科学和胶体/界面化学，以深入了解与采矿业中最主要的加工技术之一相关的固液界面特性。重点完全放在可以表征浮选化学物质（称为试剂）吸附的界面表征方法以及该吸附作用（当系统浸入溶液中时），从而最大程度地提高了研究与复杂水胶体系统的相关性。理论和实验方法论都得到了解决。
