The arrastra has been used since the Phoenicians to grind ores, most often gold or silver. The construction involves a circular pit paved with flat stones.

This arrastra at the Gold Bug Mine was powered by a waterwheel, clearly evident in the photograph. It is a cheap but effective...

At 16 level, the ore train would dump rock into the large pit (Grizzly) at the bottom of which was located a jaw crusher.

Inside the ball mill, there would be ore and steel balls, approximately 10 in. in diameter. As the mill rotated, the ore was crushed by the balls. Eventually, the balls would wear down and Bob Riggle remembers his dad...
