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 ...
DetailsThe mill machinery, all but the engine, and an order for that has been given to a Los Angeles firm, is on the ground and the work of building is ready to begin. A 10,000 gallon redwood tank is contracted for, to be placed in the top of the hill to hold the water supply for the mill, and in a little time the dropping of the first stamp in ...
DetailsThe 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 ...

DetailsThis Stamp Mill dates back to the 1800's. It has been used at several mines in the Dahlonega area as well as in other states. It was placed on the site in the 1960's. This Stamp Mill has ten stamps with each one weighing 450 lbs. each. The purpose of the Stamp Mill is to crush gold bearing rock into sand so that it can be processed.
DetailsStamp 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.
DetailsA 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.

Beckmann states that mortars, mills, and sieves were used exclusively in Germany throughout the whole of the 15th century, and in France stamps were unknown as late as the year 1579.
DetailsA stamp mill is a large mechanical device used to crush ore and extract the desired metals from the host material. It uses heavy steel stamps to crush and break apart material, releasing the valuable gold from worthless rock, allowing for the extraction of gold for further refining.
DetailsThe 1891 built Rosedale mill as it appeared in 1905. The gravity fed mill sent ore to a steam driven stamp mill for crushing the ore and an amalgamation table, and later the cyanide plant, for the gold recovery. This mill was destroyed by fire on …
DetailsSince the output from the stamp mill will require further purification. A collector metal such as lead has a much lower melting temperature than gold and gold willingly alloys with the lead. The button removed from the cooled slag then cupelled, as the lead melts the oxides shed off being absorbed into the bone ash leaving behind a button of ...
DetailsA 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.
