  • Stamp Mills for Processing Gold Silver Copper Ore

    A stamp mill is a large mechanical device used to crush ore and extract the desired metals from the host material. It uses heavy steel stamps to crush and break apart material, releasing the valuable gold from worthless rock, allowing for the extraction of gold for further refining. The basic design of a stamp mill has been used for thousands of years for a variety of crushing applications

    The stamp battery is the heart of a stamp mill and the mechanical separation process to break the various components of the ore apart, freeing the gold from its enclosing material. To start, the mined rock enters the mill and passes over a grizzly (like a grate- kit# M1 ) that has bars spaced to allow rocks that the stamp battery can handle to drop through.

    Stamp mills were used by miners in Samarkand as early as 973. They were used in medieval Persia to crush mineral ores.By the 11th century, stamp mills were in widespread use throughout the medieval Islamic world, from Islamic Spain and North Africa in the west to Central Asia in the east. The basic design has not changed by much other than the drive mechanisms.

    18/6/2015· The crushing capacity of a 3-stamp mill is around 0.3 to 0.5 tonnes/h depending on the hardness of the ore. The cleaning of a stamp mill is easy but not quick, and usually involves manually digging out all the material accumulated in the mortar box between the stamp dies. Gold, as a heavy mineral, can be accumulated in the mortar box.
