The Golden Gate Mill is a neat site and fairly easy to get to. The ten stamp mill got its ore from a 2,300 ft tramway which ran up to the mine. The gold mine was discovered in 1898 but wasnt worked until around 1902 and probably peaked in 1913. Apparently, the mill and buildings were destroyed a couple of times by avalanches. Once in 1907 and twice in 1911!
This Stamp Mill dates back to the 1800s. It has been used at several mines in the Dlonega area as well as in other states. It was placed on the site in the 1960s. 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.

The stamp mill was the big gold machine of its day. By 1850 in California all of the rivers and streams had been picked clean of placer gold. It didnt take long for miners to follow the gold deep into the Sierras steep valleys to snow white quartz outcroppings.
A small gold mine flowsheet is shown below together with cost data which clearly shows the results that can be obtained when handling a low grade ore by a simple process. There are many commendable features in such a set up and no complicated machines or practices are embodied in this plan. In fact, its simplicity is appealing and the results obtained prove the practicability of this

Quartz Stamp Milling methods of operation for gold Principles of Stamp Mill Crushing The stamp battery crushes in two ways, by compression as the result of the impact of the stamp falling upon the ore over the die, and by the abrasion or attrition of the particles of rock upon each other when moving from the impact of the stamp.

Typical late 19thcentury westernUS stamp mill The first authenticated discovery of gold occurred on the Cabarrus County farm of John Reed in 1799, sparking the nation''s first gold rush. During its peak years, more than a million dollars of gold was recovered a year, making North Carolina a leader in gold production until 1848.
Geology Gold Mines Desert Mining History Stamp Mill 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.
In 2006, we took a side trip to check out the remains of a hidden 10 stamp and cyanide mill. The mine and mill were worked around 1915. There isnt that much left of the mill
A stamp mill consists of a set of heavy steel (ironshod 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 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.
How Stamp Mills Work: A stamp mill is a large mechanical device used to crush ore and extract the desired metals from rock the host material. It uses heavy steel stamps to pound and break apart rock, releasing the valuable metals from worthless rock, allowing for the extraction of gold
Stamp mill for gold selection was invented later to make up the disadvantages of traditional panning tools, and greatly improved the quality and speed of ore beneficiation. 2, this machine prohibit strip start, the outage at boot time, you must first clean up the residual ore in
Gold ore . Prominer maintains a team of senior gold processing engineers with expertise and global experience. These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and costefficient process designs.
Stamp Mills YouTube. Mar 14, 2007 #183; This is the way gold ore is processed in Zim These mills are in Zimbabwe and to my knowledge are still this is great..wow!! to see some stamp mills
Stamp mills are used by miners to crush valuable ore and extract the metals within them. Gold, silver, and copper are common metals that are found within ore, and stamp mills allow these metals to be released from rock for further processing and refining.
