If testing shows that a finer grind liberates additional gold, the tailings from the hammer mill circuit can be stockpiled and rerun when a ball mill is installed in a more permanent installation. Ball mills routinely produce P80 of 200 mesh, in preparation for flotation or leaching, but can be tuned to produce sizes from 50 mesh and smaller.
