Optimal coal processing route for the J mm size fraction?

Optimal coal processing route for the 3 x mm size fraction? One can see from the data that the separation efficiency achieved on the fine size fractions is somewhat impaired, compared to the efficiency of separation of the coarser size ranges. The recovery efficiency is, however, still superior to some wateronly processes.
