The flotation separation between aluminum and silicon which is contained in the waste crystalline solar silicon cells was examined by semi-batch types of experiments. (1) Sodium dodecyl sulfate (SDS) permitted only aluminum powder to hydrophobize due to the difference of surface potential between silicon and aluminum.

Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process. In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment inside a flotation cell.
