Jan 23, 2012 In modern times though, mining for gold is a much intensive, yet sophisticated process. Most surface, or alluvial gold has been found, which is why gold is mainly mined from the earth today. It’s largely a matter of technology and requires much expertise and elaborate equipment. Mining for gold today can essentially be broken down into 9.
The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
At least eight of the mines boasted total production in excess of 1,000,000 ounces. Overall, hardrock mining accounted for about 60 of the gold produced in the Mother Lode and Sierra Foothills.

Gold can be found almost anywhere on the planet, and the key to recovering it is knowing what type of gold it is. Gold deposits can be grouped into two primary classes placer deposits, where the gold is exposed from weathering and erosion, and hard rock, where the gold is still trapped within the host rock.

Free gold taken from hard rock ores always contains at least a little silver, with the average gold fineness typically being in the range of around 80 percent, but it does vary quite a bit. Any associated sulfides in the ore are likely to carry silver in proportion than the native gold.
Before hard rock mining operations have even begun, companies explore areas where gold may be found and scientifically analyse the rock.

If enough gold is discovered in the ore, the technological process of hard.
It was underground, hard rock mining operations that transformed California gold mining into a corporate activity. It was in the Northern Mines, clustered around Grass Valley, which dominated underground mining. In the beginning, the gold bearing quartz was wrenched from underground veins by backbreaking, dimly lit sweat and blood.
Gold mining is either load (hard rock) or placer (loose gold that has separated from rock through natural processes). For the recreational prospector, the two most popular forms of gold prospecting are gold panning for placer gold or using a metal detector to.
