Stamp Mill Mojave Desert

Geology Gold Mines Desert Mining History 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 process explained:

Stamp Mill Mineral Processing & Metallurgy

When stamp mills are used for dry crushing, double discharge mortars are provided (see Fig. 50), and the screens are put low down, giving a small depth of discharge. These arrangements are necessitated by the difficulty of discharging the crushed ore from the mortar, the only means of doing this being the dashing of the dry ore against the screens, due to the fall of the stamps. Expediting the

(46) Operational Stamp Mills in the USA (update 9/2016)

The stamp mill is at the Crisson Gold Mine in Dahlonega, Georgia. The mine was established in 1847 and was worked commercially until the early 1980s. The operation was opened to the public in 1969. The 10-stamp mill crushes the ore through a hand fed method, and it goes onto the sluice table to a catch basin and then is panned out.

Mammoth Mill — HO model stamp mill

The original 40-stamp Mammoth Pan Mill was built in 1878-79 outside of Mammoth Lakes, California. It was only used during Mammoth's brief gold mining boom and abandoned in the early 1880s. It lay derelict until it was burnt by the U.S. Forest Service in 1929, a short time after this hand-colored photo (now in the Gene Autry Museum) was made.

Gold and Tailings: The Standard Mill at Bodie, California

At the heart of the Standard mill are the batteries of stamps that pulverized ore in order to expose particles of gold and make them available for recovery during subsequent steps in the process. The stamp mill derived its name from those stamps. It was the deafening stamps that made, by far, the most noise when a stamp mill was in operation.
