ABSTRACT
Since many mineral processes rely on the manipulation of interfacial properties, such as hydrophobocity, surface tension and wettability, there is a great deal of interest in being able to relate the micro-scale properties of the solid/fluid species to the macro-scale behaviour of the processes themselves. In order to develop this understanding, it is necessary to be able to directly measure and observe such properties, a task which can be non-trivial due to the conditions that can be encountered on the plant scale. Over several years, a range of unique devices, collectively known as Micro-Force Balances (MFBs), have been designed and constructed in the author’s laboratory, which can measure and observe micro-scale interactions between solid particles in both gaseous and liquid media, at ambient and high temperatures. Mineral processing applications such as granulation, flotation and spherical agglomeration have been the subjects of studies to date. This paper presents an overview of the MFB designs and the significant findings in relation to these applications.
