Winning the Metal: Ore Mills of the West
For hard rock, stamps might weigh as much as 750 pounds, and water to the tune of 150-200 gallons an hour was fed into each stamp to produce a slick pulp. It has been estimated that roughly ninety per cent of quartz bearing minerals were crushed by stamp mills. By 1875, California's Gold Rush country had nearly 400 mills operating.

12.9: Mining
Mining in the United States became prevalent in the 19th century, and the General Mining Act of 1872 was passed to encourage mining of federal lands. As with the California Gold Rush in the mid-19th century, mining for minerals and precious metals, along with ranching, was a driving factor in the Westward Expansion to the Pacific coast.

Gold Extraction & Recovery Processes
Chemical composition of gold particles and associations with other minerals affect gold recovery by flotation. In general, gold-pyrite or gold-copper minerals associations have no problems and gold can be recovered without major problem. The lack of good liberation is a problem and the comminution circuit is the key element.
