Mercury (Hg)
Historically, Mercury was used extensively in hydraulic gold mining in order to help the gold to sink through the flowing water-gravel mixture. Thin mercury particles may form mercury-gold amalgam and therefore increase the gold recovery rates. Large scale use of mercury stopped in the 1960s. However, mercury is still used in small scale, often clandestine, gold prospection. Total use of mercury in placer mining in California has been estimated to more than 4500 tons (10,000,000 lbs). Mercury was also used in silver mining. And in the process of gilding (gold plating) silver plate.
Cyanide (HCN)
Cyanide solutions are used in the extraction of gold from low grade ore. The reaction in the Elsner Equation is as follows :
4Au + 8NaCN + O2 + 2H2O -> 4NaAu(CN)2 + NaOH
The gold is then recovered from the the soluble aurocyanide complex by plating out.
An Aside: Walking across tailings area you can smell the sweet cyanide aroma
Aqua Regia (HNO3 + HCl Solution)
This is the historic method of dissolving gold . Higraders in gold camps ofhen are found by watching chimneys to see the brown nitrous fumes from boilling off the acid to recover the gold.
What else can I help you with?
How does gold react with sodium bromide?
Gold does not react with sodium bromide under normal conditions. Gold is a noble metal and is relatively unreactive with other elements, including sodium bromide.
Does Argon react with any elements?
It can react with Hydrogen, Litium and some unknown elements.
What does not react with chlorine?
Elements like noble gases (e.g. helium, neon, argon) do not react with chlorine due to their stable electronic configurations. Additionally, elements like gold and platinum are also unreactive with chlorine.
What could happen if gold is placed in dilute hydrochloric acid?
Nothing, gold does not react with hydrochloric acid, if there are impurities of other metals in gold then impurities may react and form chloride salts.
Which metal don't react with bromine?
Bromine, which is represented by the chemical symbol Br, is very corrosive with most other elements. The only element I could find it does not react with is water.
How does gold react with sodium bromide?
Gold does not react with sodium bromide under normal conditions. Gold is a noble metal and is relatively unreactive with other elements, including sodium bromide.
Is metal least likely to react with other elements?
It depends on the metal. Gold will react with other elements with great difficulty. There are gold compounds, but if you have a solid chunk of gold it'll basically sit there and do nothing. Titanium and aluminum are pretty reactive. Iron reacts pretty well with oxygen. At the far end of the scale, sodium goes out of its way to react with other elements.

Why gold and platinum are called noble metals?
Because they don't react with other elements.
What elements would not react because it is already stable?
The noble gasses, gold and platinum.
What are the elements which don't react with any other elements or compounds?
The Noble gasses.
What does gold element react with?
Gold reacts with few elements including chlorine, oxygen and fluorine under critical conditions.
Does arsenic react with any other elements?
yes
Does gold contain any elements?
Gold is an element
Is gold nontoxic?
Gold is nontoxic. It doesn't react to any organs in the body. :)
Does Argon react with any elements?
It can react with Hydrogen, Litium and some unknown elements.
What is the part of the periodic table that has elements that do not chemically react?
All of them tend not to react with each other until you get lower down the group
