Ore Milling - Mt Baker Mining and Metals

Small-scale hard rock miners do not have the luxury of a fully equipped industrial-grade mill with flotation and cyanide leaching to their and recover values. We are usually limited by practicality, finances and permitting to a simple crushing and grinding circuit, with a gravity recovery system for the free values and value-containing sulfides.

    Before the advent of heavy machinery the raw ore was broken up using hammers wielded by hand, a process called "spalling". Before long, mechanical means were found to achieve this. For instance, stamp mills were used in Samarkand as early as 973. They were also in use in medieval Persia. 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. A later example was the Cornish stamps, consisti…
