Crushing/Quartz Ore Mining Method. The crushing method employed a crushing device called arrastra. The device was essentially made of stones arranged in a circular pattern to hod the gold-bearing ore. A strong post was driven to the ground at the center. This pole acted as the pivot for another pole which was driven by a mule to pull a very ...
