Process in stirred media mills In the stress model of the mill, the following aspects are involved: The crushing behaviour of the mill is defined by the kind of stresses (such as shear forces, impact, and compression), the frequency of the stress events, and the energy, which are supplied by the mill at each stress event, the so-called stress .

Furthermore, the presence of the “Nugget Effect” (where the bulk of the gold content is found in a few sporadic nuggets) can cause erratic fire assay results.When analytical samples are prepared, small amounts (10 grams, Clifton.1969) of samples are randomly chosen to be analyzed by fire assay or by atomic adsorption .
