Description: Original title The Interior. "Clean Up" day at the Deadwood Terra Gold Stamp Mill, one of the Homestake Mills, Terraville, Dakota
Interior of the Deadwood Terra Gold Stamp mill. Crushed ore is washed over mercury coated copper sheets, whence fine gold particles form an almagam with the mercury. The amalgam was scraped off and the gold then separated from the amalgam by heating and evaporating the mercury which was then recovered by a condenser for reapplication to the plates
