Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
Using mineralogical characterisation and process modelling
In the present example using SG Heavy mineral ∼ 6.5 and SG Light mineral ∼ 3.2, the CC is calculated to be 2.5, indiing that gravity separation is an appropriate method of concentration for size classes coarser than 75 μm. Fig. 8 shows the size by density distributions of the three main alloys and the three main gangue phases. The
