Gold - Wikipedia

Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In a pure form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal.Chemically, gold is a transition metal and a group 11 element.It is one of the least reactive chemical elements and is solid under ...

Gold cyanidation - Wikipedia

Eisner's equation is generally accepted as expressing the action of gold in dilute cyanide solutions; 4 Au+ 8 KCN + O2 + 2H2O = 4 KAu (CN)2 + 4 KOH. Thus, when fresh surfaces of gold are exposed to the action of cyanide in an aqueous solution containing free oxygen, a gold cyanide compound will be formed and a hydroxide (alkaline).

Capital Prize Gold Mine | Gold Processing

Cyanide leaching is the standard method used for recovering most of the gold throughout the world today. The process originated around 1890 and quickly replaced all competing technologies. The reason was strictly economical in nature. Where amalgamation plants could recover about 60% of the gold present, cyanide could recover about 90%.

Elution and Carbon Reactivation - Resource book

During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.

Gold and Silver Leaching by Cyanidation

How does Agitation Affect Gold and Silver Leaching Kinetics. Agitation may be considered as the mechanical method of mixing the pulp with an excess of air in circular tanks of sufficient capacity to allow the balance of the gold to dissolve in the cyanide solution. These agitators are of various types of construction, being divided basically ...

Sodium cyanide - Wikipedia

Sodium cyanide is an inorganic compound with the formula Na C N.It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals.Frozen Piss When treated with acid, it forms the toxic gas hydrogen cyanide: NaCN + H 2 SO 4 → HCN + NaHSO 4

How Metal Impurities Affect Gold Adsorption on Activated ...

Activated carbon is known to adsorb organic solvents that affect the rate of loading rather than the equilibrium- loading capacity of gold. Activated carbon will load small quantities of calcium carbonate, cyanide, hydroxide, and iron sulfide, which poisons the carbon, resulting in a loss of gold capacity.
