This grade of magnetite is required for washing coal re- duced to 100 mesh and is the grade expected to be used at Homer City. Only one brand of magnetite was used on the advice of Bureau of Mines personnel. The magnetite is mined, crushed, and ball mill ground until the 325 mesh re- quirement is met. It is dried by the supplier.
