abstract
The stability of the thin ?lms found in the froth phase of ?otation plays an important role in the overall ef?ciency of the separation process. In turn, the physical behaviour of the particles attached to the ?lms has a direct impact on the lamella stability. This effect is not fully understood. The ?lm solids loading, or attached mass to area ratio, is an indicator of froth stability and has been measured by touch sampling of surface bubbles. Multiple samples can also be assayed as an indicator of maximum possible grade. Here the touch sample technique is used to show the particle packing arrangement on the ?lm. This work presents images of touch samples from the top of the froth viewed under a Scanning Electron Microscope (SEM). Froth samples were obtained during batch ?otation of glass beads with a size fraction of 90–
150 lm. The packing arrangement of the particles attached to the surface lamellae were clearly resolved,
making it possible to obtain a measure of ?lm packing density using image analysis. These results can be used to validate and expand physical models that predict ?lm stability.

1. Introduction
Sampling the surface lamellae of a ?otation froth is done using the touch sample method, devised by Sadr-Kazemi and Cilliers (2000) to measure the ?lm solids loading and grade. The technique employs a clean microscope slide which is used to burst a bubble, leaving behind an imprint of the
