Gold processing Britannica

Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstromsget price

Gold mining Wikipedia

OverviewGold ore processingHistoryStatisticsMethodsBusinessAdverse effectsSafety

In placer mines, the gold is recovered by gravity separation. For hard rock mining, other methods are usually used. Cyanide extraction of gold may be used in areas where fine gold-bearing rocks are found. Sodium cyanide solution is mixed with finely ground rock that is proven to contain gold or silver, and is then separated from the ground rock as gold cyanide or silver cyanide solution. Zincis added to precipitate out residual get price

How Is Gold Extracted From Gold Ore? Sciencing

Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold get price

But the amount of gold in the earth is extremely small, so that mining is not really worthwhile. Generally there are two types of gold: primary gold (“mountain gold” from mines) and secondary gold (“stream gold”,“nuggets”). Above all the extraction of primary gold is associated with considerable effort. There are various methods to free...

Extracting Gold HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled withget price
