Stamp Mill. When stamp mills are used for dry crushing, double discharge mortars are provided (see Fig. 50), and the screens are put low down, giving a small depth of discharge. These arrangements are necessitated by the difficulty of discharging the crushed ore from the mortar, the only means of doing this being the dashing of the dry ore ...

The tests were encouraging enough to merit rebuilding the cyanide plant one-half mile north of the stamp mill according to the newly devised flow sheet. Construction took place during summer 1904. After a year of fine-tuning, Standard had its new cyanide plant running on a regular basis, treating all the ongoing production of tailings, to which ...

Stamp Mill Project. Bodie's Stamp Mill, one of the best intact stamp mills from the late 1800s in the West, needs mountains of work to keep it standing. This will likely be a 10-year project. The first stage will be the removal of dirt and rocks from the hillside that are causing structural issues, and the repair of collapsing floors.

A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam.

A stamp mill was a mechanical crusher, noisy, heavy and somewhat awkward to operate. The stamps were heavy metal weights that were lifted and dropped on the ore by a crankshaft. The crushed ore would then be further refined, usually by a mercury or cyanide process. The miner would bring the ore to the mill and load it into the ore car.
