Gold is a soft metal that is largely unreactive. Gold jewellery can lie underground for thousands of years and emerge shiny after that lengthy exposure to air, water, and other chemicals in the environment. Gold does dissolve in some solvents as indicated below and does react with halogens. The most common oxidation states of gold are Au (I ...

chemical equation for gold ore mining

The chemical reaction for the dissolution of gold, the "Elsner Equation", follows: 4 Au (s) + 8 NaCN (aq) + O 2 (g) + 2H 2 O (l)→ 4 Na [Au (CN) 2 ] (aq) + 4 NaOH (aq) In this redox process, oxygen removes, via a two-step reaction, one electron from each gold

How gold is made

Gold, recognizable by its yellowish cast, is one of the oldest metals used by humans. As far back as the Neolithic period, humans have collected gold from stream beds, and the actual mining of gold can be traced as far back as 3500 B.C., when early Egyptians (the Sumerian culture of Mesopotamia) used mined gold to craft elaborate jewelry, religious artifacts, and utensils such as goblets.

Activated Carbon in Gold Cyanidation

The gold cyanidation process is a primary method of gold beneficiation. Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation.

Copper Mining and Extraction Sulfide Ores

Gold, silver, platinum and tin are insoluble in this electrolyte and so do not deposit on the cathode. They form a valuable ''sludge'' that collects under the anodes. Soluble impurities of iron and nickel dissolve in the electrolyte, which has to be continually purified to prevent excessive deposition onto the cathodes, which would reduce the purity of the copper.
