A 62.5-percent solids discharge from the rod mill is sized in a spiral classifier operating in closed circuit with a ball mill. The sands are reground in the ball mill, and the pulp containing 80-percent, minus 150 mesh is pumped to a conditioner where 0.2 pound of KAX and 0.36 pound of MIBC per ton of slag are added.
