Above and below the rocker or cradle was a simple way of straining gold from lighter rock. Mexican miners used the horse drawn arrastre to crush gold bearing rock.

Jun 12, 2006As the mining camps played out, and anti Chinese sentiments drove many immigrants out of the smaller towns in the West, the Chinese migrated toward the coastal cities. Even in towns like Chico, Calif., which once had an extensive Chinatown, and Folsom, Calif., home to over 3,500 Chinese in the latter part of the 19th century, only the most
Women in the California Gold Rush, which began in Northern California in 1848, initially included Spanish descendants, or Californios, who already lived in California, Native American women, and rapidly arriving immigrant women from all over the world.At first, the numbers of immigrant women were scarce, but they contributed to their community nonetheless.
A few years after the Gold Rush began, Chinese immigrants began to be treated terribly. One major reason for this was that the gold mines were starting to become exhausted. The newest gold miners were not able to find gold and become rich as easily as they had expected to, leading them to feel disappointed and angry.
Other mining claims for African Americans would be found around the gold country from Downieville in the north to the southern mines in Calaveras and Mariposa Counties. 1850 California becomes the nation's 31st state as a result of the Compromise of 1850 where it is agreed that California would enter the Union as a free state.
Although this may be a natural side effect of the economic forces at work, there are many who would not appreciate further concentration in the hands of the Chinese mining firms and pools. Given that the power prices will be artificially low by international standards, it will mean that more miners will be able to hash out much more supply.

Folsom History. The progressive nature of Folsom currently could give the impression of a relatively new city but, in fact, Folsom is one of the older cities in Northern California and is very proud of its past. The first known European to explore the area we now call Folsom came with a
The Gold Jig or Mineral Jigs are important of all types of alluvial gold concentrating device among all gravity separation methods; they are also the most complex and the practice of jigging in mineral processing is often viewed as an art rather than a science. Gold jigging has been referred to as being probably the most complex gravity operation because of its continuously varying hydrodynamics.
