Jul 12, 2018#0183;#32;In the early days of mining stamp mills were used to crush the ore prior to gold recovery. A stamp mill is a very simple machine. The flywheel builds momentum to turn the cam. The cam lifts the stamps and then gravity drops them back down at a rate of 40 times per minute. It can process approximately 1 ton of rock per hour.
Stamps drop at a rate of about 100 per minute and grind about 3 to 5 tons of rock per stamp per 24 hr. Water consumption averages around tons per ton of ore. The stamp mill was originally devised as a combination grinding and amalgamating device before the days of cyanidation.
Oct 21, 2011#0183;#32;An incline shaft of 1,000 was sunk and off that a 2,000 horizontal shaft hit the best paydirt. At its climax the mine employed a 40 stamp mill. Its ore averaged better than 20 per ton. Total take of the mine was conservatively place at 3,500,000 and some say it was more like 5,000,000.
At the present moment, using steam power, we may take, therefore, the cost of milling, milling, etc., at the abovementioned figure, viz., per ton. #171; Back to the Stamp Mill On to the Assay Office #187;

The Stamp Mill is a very simple machine. The flywheel builds momentum to turn the cam. The cam lifts the stamps and then gravity drops them back down at a rate of 40 times per minute. It can process approximately 1 ton of rock per hour. There are several ways to power a Stamp Mill. One way is a water wheel. Another way is a steam engine.
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.
The Mohawk Mining Company was a major copper mining company, based in the Keweenaw Peninsula of Michigan, that was established in November 1898 and lasted until company, between 1906 and 1932, paid out more than 15 million in shareholder dividends. The Mine is best known for the large amounts of mohawkite that were found on the property. The Mohawk mine operated until 1932; in

Aug 28, 2014#0183;#32;Ore was transported from the seven Luck Bart Mine tuneels by sled, then ore car to this stamp mill. Milling continued intermittently, as ore became available, until the late 1930s. As of 1938 the mill had crushed and processed 14,000 tons of ore with values running from 8 to 12 ounces of gold per ton.
At that time, gold was 18 to 19 an ounce. An ore cart holds roughly one ton of quartz ore. Poor management resulted in few profits. Cossak Mining Company. Cossak Mining Co. operated the mining efforts in the area from and built this fourbank stamp mill into a 35foothigh building on the side of a canyon wall. The mills were
Stamps are built heavy, made from steel or cast iron heavy enough to pulverize the ore beneath. The stamps are repeatedly raised and dropped onto ore that is fed into the mill, until the coarse ore is reduced to finer material capable of further processing. The stamp mill provided an invaluable need for the early gold miners.

If we do some more work on numbers using the Bodie stamp mill as an example 3 tons of ore processed/day/stamp = 15 tons/day for a 5 stamp mill. Using the US short ton of 2000 lb, that''s 30,000 lb of ore needed daily to keep the stamp mill running flat out. That''s only about 1/2 a gondola load/day of ore.
Mining costs averaged about per ton since 1932. The first mill reached a capacity of 60 tons daily in 1937. A large mill was then installed. By 1940, production had increased to 140 tons of ore mined and milled every 24 hours. Machinery included a jaw crusher and rolls at the mine, and a ball mill
