An arrastre was a simple machine, powered by animals or motors, designed to speed up the crushing of quartz ore. The ore was placed in the bottom of the arrastre over which were placed large rocks. The rocks were ground over the ore, crushing it and releasing the gold.
From Wikipedia, the free encyclopedia Gold miners excavate an eroded bluff with jets of water at a placer mine in Dutch Flat, California sometime between 1857 and 1870. Gold extraction refers to the processes required to extract gold from its ores.
Unlike placer mining, gold that is mined from lode sources require crushing to extract the gold from rock. The basic design generally used two large flat stones that were dragged around a circular pit made from flat stones. The drag stones were attached to a central pivot which allowed them to be dragged repeatedly over the ore that was placed in the arrastra.

Historical records indicate that about 3,000,000 lb of mercury were lost at hardrock mines, where gold ore was crushed using stamp mills (Churchill, 2000). Mercury was also used extensively at drift mines and in dredging operations. Mercury was used widely until the early 1960s in the dredging of auriferous sediment from alluvial flood-plain deposits. Today, mercury is recovered as a by ...
Cordwood stacked at right produced steam that powered the mill's ore-crushing machinery.

By 1988, when California’s annual gold production exceeded 732,000 ounces ($320 million) most of the gold came from fifteen large open pit mines. The most productive of California’s revitalized mines were not in the Sierran gold country, but in the Coast Ranges in Napa and Yolo counties, north of San Francisco. This is an area long mined, not for gold, but for mercury. One of these, the ...
