MILLS USED IN MINING. Stamp mills were used in mining to crush ore from deep deposits into small pieces before further processing. The metal ores needed to be crushed down to a pea or walnut size before it could be smelted. At times, the mills were also used in metal working after the completion of the smelting while the metal was red hot.
