The application of the FGX dry coal separator mining technology can be schematically shown to the right.

The FGX separator typically generates three product streams, i.e., clean product, middlings and tailings.  In each of the scenarios discussed above, coal blending can be performed to maximize the economic benefits of an operation.  Options of blending include blending FGX middlings with clean product, blending FGX deshaled product with prep plant clean coal, etc. A clean product that can be sold directly without further processing is also achieved in many instances.
