A system of rotating shaft and cam is used to raise and lower the stamps on top of the ore. 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.
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. The rock was then separated into poor rock, left over or waste rock, and ore, the rock that contained copper.
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.

Copper can be found in sizes from the head of a pin to many pounds, but small pieces with more rock than copper is the rule. The largest specimen of solid copper, with no rock, that we have found is a piece of glacial float copper found with a metal detector that weighs 300+ lbs. Float copper pieces weighing multiple tons have been uncovered
As one of the largest copper producers in the United States, Rio Tinto Kennecott comprises approximately 11 percent of U.S. annual copper production. The Bingham Canyon Mine is one of the top producing copper mines in the world with production at more than 20 million tons. The Bingham Canyon Mine is the largest man-made excavation []

Copper use in the regions surrounding Lake Superior represents processing (i.e. stamp mill, smelting, annealing, etc.). Runoff Europeans to pieces of float copper, there is no record of active cop-per mines (Whittlesey, 1863) or successful copper mining activity
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

A photograph of the Tube Mill of William Tonks & Sons included in their 1939 and earlier catalogues, 'as enlarged and electrified'. The draw benches were used to draw lengths of tube through the dies, frequently with a floating mandrel inside to retain the shape of the tube as its diameter was reduced.
When stock comes in with heavy mill oil, the lubricant must be able to work on that oil surface. This can be a problem for oil-free chemical solutions, because these products need to reach the metal surface to provide lubrication but tend to float off an oily surface. A roller coater helps work the chemical solution through the oil coating.

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. The crushed ore would then be further refined, usually by a mercury or cyanide process. The recovery table was a copper-sheeted table that was coated
