The mineralogical limiting curve u(Rg) describes the theoretical
limit for separation processes. Due to the lack of powerful systems
to measure this curve in the past, the model was limited to the calculation
of B using total liberation of valuables as theoretical limit.
Today 2D liberation analysis can be used to find the mineralogical
limiting curve. Thus the model can be improved by the calculation
of a more precise separation parameter and extended by the calculation
of a liberation parameter.
