That sounds like a logical way to process the tailings , I just find it strange that the machine they are using to regrind is the same ball mill that initially processed the ore , its interesting they did not use a cyclone the first time around to put the oversize back through the ball mill.
I wonder if that was an issue with grinding to fine and lowering flotation recoveries when skimming .
Also its interesting they are going to use a ball mill rather than an isa mill to do the initial fine grinding .
Anyway hope it works out well for you they seem to have people with plenty of expertise on metallurgy working for the company , I have no academic qualifications /experience in that field
