Framed Print of Gold stamp mill, USA, 1888
Gold stamp mill. Workers cleaning the inside of a stamp mill used to obtain gold from crushed ore. After crushing (at right), the ore was washed over mercury-coated copper sheets (at left). The resulting amalgam (mercury alloy) of the gold particles with the mercury was scraped off. The gold metal was then recovered by heating and evaporating the mercury, which was itself trapped in a condenser for reuse on more ore. This is the Deadwood Terra Gold Stamp Mill, one of the mills operated by the Homestake Mining Company in Terraville, Dakota, USA. This photograph, by John C. H. Grabill, dates from 1888.
