Does sulphuric acid remove copper from gold?
Sulfuric acid is not typically used to remove copper from gold, as it can also affect the gold itself. Other methods, such as leaching with cyanide or nitric acid, are commonly used to separate copper from gold. These methods are more selective in targeting the copper without damaging the gold.
What is the Merrill-Crowe process chemical equation?
The Merrill-Crowe process is a method used for the precipitation of gold and silver from cyanide solutions. The chemical equation for the process involves the addition of zinc dust to the solution, which reacts with the gold and silver cyanide complexes, forming a zinc-gold/silver precipitate and releasing cyanide ions back into the solution to be reused.
How do you extract gold from copper ore?
Gold can be extracted from copper ore through a process called cyanidation, where a cyanide solution is used to dissolve the gold from the ore. The resulting solution is then processed to recover the gold through a series of chemical and physical processes.
What is the difference between silver cyanide and gold cyanide?
The cyanide radical consists of a carbon atom triple bonded to a nitrogen atom, and has a -1 charge. It's CN- as we write it. The only difference between silver and gold cyanide is the silver and the gold. Both precious metals will form a bond with the radical in their +1 valence state, so the observer will see either AgCN or AuCN molecules. The former is, of course, silver cyanide, and the latter is gold cyanide.
What is AuCN3?
AuCN3 is the chemical formula for gold(III) cyanide, which is a coordination compound made up of gold ions bonded to cyanide ligands. It is a highly toxic substance primarily used in gold electroplating and as a reagent in chemical synthesis.
Why is zinc and not copper is used for the recovery of silver from cyanide complex?
Zinc is used for the recovery of silver from cyanide complex because zinc has a stronger affinity for cyanide compared to silver. When zinc is added to the cyanide solution, it displaces silver from the complex, forming insoluble silver-zinc alloy particles that can be easily separated. Copper is not used because it does not have a strong enough affinity for cyanide to displace silver effectively.

What is cyandie used for?
Cyanide is a poison, and Hydrogen Cyanide is often used to purify gold.

Is the 24k electroplate golden 49er series pure gold?
Yes and no. One common chemical used in electro plating is gold cyanide. By applying an electrical current to copper or silver submerged in gold cyanide, a thin layer of gold is deposited on the object. It may be 24K, but is so thin it can be scraped off, and has virtually no value.
What environmental concerns with gold?
when gold is being cleaned and extracted cyanide solution is used. cyanide is a poison to people, animals, and fish. cyanide can leach through to underground water and poison the water. when gold is being cleaned and extracted cyanide solution is used. cyanide is a poison to people, animals, and fish. cyanide can leach through to underground water and poison the water.
Is cyanide found in Gold and silver mining operations?
No. It is used in the refining and fracturing processing the ore to get the Gold out of the base rock. Cyanide is used in a utility capacity, it is not a Gold or Silver by-product.

In the electroplating of gold the electolyte used is?
Gold-VA is a strong acidic cyanide based gold-electrolyte.It is used in gold plating.
