California Gold Rush | Definition, History, & Facts
By August 1848, 4,000 gold miners were in the area, and within a year about 80,000 "forty-niners" (as the fortune seekers of 1849 were called) had arrived at the California goldfields. By 1853 their numbers had grown to 250,000. Although it was estimated that some $2 billion in gold was extracted, few of the prospectors struck it rich. The work was hard, prices were high, and living conditions were primitive.

From ore to doré. Cyanidation. More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat
