On the size dependence of the King stratification index
The study reported in this paper addresses an aspect of the modelling of particle stratification as it applies to the processing of minerals. It focuses on the phenomenological model developed by King and the extent to which the single parameter in that model, i.e. the stratification index, is dependent on the size of particles in the stratifying system.

The exception to this is when a mineral is brittle. When testing your mineral's hardness, you may notice that when you try to scratch it with a harder substance the mineral turns to a powder. This means the mineral is brittle and there is no further testing needed to determine its tenacity. Thankfully, most minerals are brittle.
