Stamp Mill Crisson Gold Mine

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 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.

Stamp Mill – Explore Real California Gold Mines!

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 didn’t take long for miners to follow the gold deep into the Sierra’s steep valleys to snow white quartz outcroppings. They soon realized the gold trapped within these veins could produce thousands of ounces of gold and thus began hard rock or ‘lode’ mining. Stamps

Gold and Tailings: The Standard Mill at Bodie, California ...

A California stamp mill was a building housing all the basic equipment needed to crush ore and recover gold and silver. Typically set into a hillside so material could move through most stages in the process by gravity, the mill received ore on the uphill side. Ore delivered to the mill dropped on “grizzlies”—a series of parallel iron bars spaced a couple inches apart that allowed the finer ore to drop into ore bins and
