In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system. The situation is further complicated by the 'mill reject' streams that reject undesirable material (tramp metal and non-coal bearing rock) from the mill.
