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.

Pug mills are often used for processing steel by-products in the form of dust and scale to liberate iron ore. In addition to the equipment above, FEECO also manufactures rotary dryers and material handling equipment, including belt conveyors, bucket elevators, steep incline conveyors, and reversing shuttle conveyors for iron ore.
A consideration of these principles will show wherein stamp-mill crushing is radically different from all other forms of rock-reduction, will point out. why the limit of economy can be passed in fine breaking in the rock-breaker, and will indicate why a fine or a soft talcose ore often requires the addition of coarse or hard ore to act as the
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

Our heavy-duty iron ore balling drums are relied on by some of the industry’s top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product

The mine had ten shafts, the deepest of which extended to a depth of 1200 feet (366 m). In 1856, miners tunneled into a 527-ton mass of native copper, the second-largest such mass found in the Copper Country. Besides masses of copper recovered through hand-sorting, the mine ran a small stamp mill to recover finer-grained copper in ore that ran 3%.

The US iron and steel industry has paralleled the industry in other countries in technological developments. In the 1800s, the US switched from charcoal to coke in ore smelting, adopted the Bessemer process, and saw the rise of very large integrated steel mills.In the 20th century, the US industry successively adopted the open hearth furnace, then the basic oxygen steelmaking process.
