Stamp mill

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.

Rock Crushing methods and How to recover gold from Ores

A slightly different version of mortar and pestle work is a variety called hand stamp crushing. A heavy cylinder of iron is welded to a long rod and placed inside a pipe or tube which is just a bit larger than the diameter of the iron cylinder. This iron cylinder is picked up and dropped onto the ore, much in the manner of the old time stamp mills.

Assaying Ores to determine gold content

The famous fire assay has been around for more than 500 years, but it still is the best method for determining the quantity of gold in a rock matrix. The fire assay process works by fusing or dissolving the rock sample in a crucible using a lead glass flux. Fluxes of various types are used on various types of ores.
