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.
A stamp mill (or stamp battery or stamping mill) is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation . Description Detail of Californian stamp showing offset cam and rotating lifter

Hydrocyclones demonstrate a trait that is useful for gold mills—minerals with higher specific gravities have a progressively finer cutsize (whether this is desired or not). In plants with freemilling gold, this leads to gold concentrating in the milling circuits (see Figure ). On a sizebysize basis, concentrations of up to 100 times ...
Hence, a mill is a piece of equipment used to grind ores. Its major purpose is to perform the grinding and blending of rocks and ores to release any freegold that is contained within them. At major mines, the mill was the critical equipment that was required to process the ores that were extracted from deep underground.
It utilizes the specific gravity difference between gold and other minerals to separate gold. It works better when processing placer gold. It is also used to separate the iron, tin, wolframite, tantalum, niobium, chromite, rutile, monazite, etc. The material size ranges from Compared with the gold shaker table, it is lighter and ...
