There was not much left in the engine Mill house except for the base of a Chilean mill and the boiler chimney. The operations were from 1854 to about 1899 according to the historical data. The mill house evolved over the years as the mining processes changed. The drawing below shows the location of the various components locations.
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 process explained: The miner would bring the ore to the mill and load it ...
The new owners erected a twenty stamp mill on the property and changed the name of the claim now known as Bunker Hill to The Standard Consolidated Company. These new owners took out the enormous sum of 6,396,270. The total production of all mining done in Bodie is estimated to be between 95 and 100 million. Source:Cain, Ella M.,

This is a stamp mill, a 19thcentury invention that saved miners from extracting precious minerals by hand, which took far more time and effort. The stamping process recreated at the Cave Creek Museum 's Arizona Gold Mining Experience was used at the turn of the 20th century across much of Arizona, which has a storied history of mining.
Cornish stamps are stamp mills that were developed in Cornwall for use in tin mining in around 1850. Cornish stamps were used to crush small lumps of ore into sandlike material. The stamp was constructed from heavy timber with an iron "head" at the bottom.
Haßfurt ( German pronunciation: [ˈhasˌfʊʁt] ⓘ; English: Hassfurt) is a town in Bavaria, Germany, capital of the Haßberge district.

Ore from hardrock mines needed to be processed to separate the gold from the waste rock. The most common method used at the time was the stamp mill. Pictured below are the stamp mills of Terraville in 1888. Note the massive piles of wood that were used to feed the boilers that powered these facilities.
Since 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 ...

Many early mines used stamp mills, but many operations today find that ball mills ...
Documenting a stamp mill is a daunting, and sometimes intimidating task. The basic purpose of an archaeological recording is to identify what artifacts exist at a site, to document their condition, and finally where they are located in space. Archaeological recording can occur both at the submeter scale, as well as at the broader landscape scale often used when documenting mine sites due to ...
Ginormous Stamp Mill Ruins. EarthCache. At this site you will see a mill stamper. These were used during the mining years to crush rock that was pulled up from the mines.

1. 2. From the 1850s to the 1920s, gold and silver mining drove Colorado's economy, making it into an urbanized, industrial state. The rapid development of Colorado's mineral resources had political, social, and environmental consequences. The mining of gold and silver in Colorado began in earnest during the Colorado Gold Rush of 185859.
Stamps were the most common way to crush ore for many decades, but by the first few decades of the 1900s the ball mill started replacing stamps. By the 1930s, many stamp mills were retrofitted with ball crushers, replacing the stamps that were originally used. While stamp mills throughout the west were similar in how they crushed the ore, the ...

A 20stamp mill was erected in 1865 on the Kern River, but the mill proved inefficient and only ran a short time. Mines in Keyesville were idle until a 1897 revival. During this time a 5stamp mill was erected at the Keyes mine and a 10stamp mill at the Mammoth. Both mines were intermittently active until about World War II.
One simple stamp was left in operation.

Numerous mines like this one once fueled Grass Valley's economy, and today, Gold Rush artifacts are part of the town's character: A stamp mill, once used to break up goldbearing rock, now guards an intersection on Main Street, and old ore carts and other rusty remnants can be spotted in parking lots and storefronts around town.
The finished model stands six feet high, and has four stories of simulated operation from crushing the stone to sorting the fines. We hid the motor in the pedestal, and used a one minute push button timer switch to activate the mill. The working model accurately shows viewers how difficult the gold extraction process really is.
Because stamp mills require water and mines typically were on mountaintops without water access, miners built tramways to transfer ore in buckets from mines to the stamp mill at a lower elevation. The Golden Reef Stamp Mill was built in 1910 on Continental Mountain northeast of town.
Hard rock miners had to mill, or crush the quartz ore. They worked stamp mills to pulverize the ore to a powder. Early stamp mills had two to five stamps. Later, banks of forty or more were used. Gold was then separated from this fine powder by the use of mercury, or quicksilver as it was called.
