Additional Details:
When gold is found in quartz there is the problem of separation from the rock. A mill was built with heavy stamps that was raised and lowered on the rock that was fed from a hopper above the mill. The crushed rock and powder fell into an ore car below the stamps and was taken to a separation tank. These mills ran night and day, the noise could be heard for miles and they seem to shake the earth with their steady pounding. Mining is older than agriculture or weaving. Throughout history the mining industry has been essential to the growth of civilization.
