In the ancient world gold was mined mainly from alluvial occurrences using gravity methods combined with the use of mercury amalgamation, a method that is still used today in small-scale alluvial gold mines worldwide. Cyanide, which was first used in the 1880s, is used in large-scale hardrock mines to recover gold, silver, copper, and other metals from porphyry and disseminated ore deposits.
Lode mining of gold became important in the 1860s, and between 1884 and 1918 gold quartz veins were the major source of Californias gold production. From the time of the introduction of the process in about 1895, treatment of quartz ores with cyanide revolutionized the industry, greatly increasing the recovery of gold from the ores.

Smelting is a method of obtaining refined goods from raw materials by heating in a furnace, blast furnace, or smoker. For example, raw iron can be smelted to produce iron ingots using coal as fuel. Like crafting, smelting uses recipes to determine what item is produced, but its recipes are simpler. Smelting also yields experience. The furnace, blast furnace, and smoker share a similar ...
The Bodie mining district is not contiguous with Californias primary quartz mining areas, and its discovery and development occurred later. During the first couple years of the famed 1849 California gold rush, individuals and small companies of miners staked mining claims along streams on the western slope of the Sierra Nevada.
The ores, however, are treated by blast furnace smelting and the gold is afterwards recovered from the copper matte. The gold content of the ore varies from 0 4 t-o afcou 15 ounces per t r tlsilver varies from 0-3 to 25 ounce per ton the copper from 07 to about 3-5 . Ores containing higher values in gold, or more copper, have been ...
The process is applicable directly to gold- bearing sand, and to gold-bearing rocks after crushing. The crushing is effected by stone-crushers, rolling-mills, and stamp-mills. The washing is carried out either by subjecting the material to the prolonged action of flowing water, or by mechanical agitation with water in deep iron pans or cradles.

You need quartz with at least 10 parts per million silver in order to smelt it using pre-modern techniques. This number was derived by comparing silver yields from smelting with silver concentrations determined by x-ray fluorescence and atomic adsorption Enderlin, 1993 Helm, 2000. Samples came from the Silverado Mine and its environs.
The California gold rush of the 1800s continues today with small miners mining for gold and silver in more than 5,000 mining claims and where rockhounders search for rocks
