Parameters for Mineral liberation
Mineral liberation is probably the most important factor associated with mineral comminution and concentrating flowsheets. This phenomenon is intimately associated with the mineralogical texture of the ore and the complex interplay between comminution and texture. The models that are required to describe this effect quantitatively are naturally complex but they are particularly suited to the population balance method and therefore fit into MODSIM comfortably. In Module 7 you were introduced to the Andrews-Mika diagram and its use for the accurate and consistent simulation of liberation effects. In this example you will see how we go about measuring the liberation characteristics of an ore using image analysis techniques applied to samples collected on an operating plant.
You should read through to the end of the project description to find the suggested modification that you can make to this plant to remove the undesirable recirculation of the liberated magnetite
