React the mixture with H2SO4 because copper is more reactive and a mettalic oxide so it would displace H2 from H2SO4 which would escape out in form of gas and CuSO4 would form . Then mix the mixture with water of CuSO4 and gold formed above . CuSO4 would get mix with water and filter out gold with filtration which is insoluble in water.

How do you separate copper fillings from a mixture of copper fillings and iron fillings?

One way to separate copper filings from a mixture of copper and iron filings is by using a magnet. Since iron filings are attracted to magnets while copper filings are not, you can use a magnet to pull out the iron filings, leaving the copper filings behind.


How can you separate sawdust and iron fillings?

To separate sawdust and iron fillings, you can use a magnet to attract and separate the iron fillings from the sawdust. The iron fillings will be drawn towards the magnet, allowing you to easily separate them from the sawdust.


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.


Could you Devise the experiment that will allow you to separate mixture of copper fillings and salt?

1 take the mixture of salt and sand and immerse them in water. 2 run the water and sand through a filter that separates out the sand. 3 store the sand. 4 boil the water until it has all evaporated or just wait for it to evaporate naturally. This will leave a residue on the bottom of the container which Will be the salt


What removes copper from gold?

One common method to remove copper from gold is through a process called cupellation, where the gold-copper alloy is heated in a furnace with lead, which combines with the copper to form a separate layer called "dore." Another method is through electrolysis, where an electric current is passed through the gold-copper alloy in a solution to separate the copper ions from the gold.

Why is gold and silver in copper?

It isn't, gold(Au) , silver(Ag) and copper(Cu) are all separate elements. But if you're talking about when they add copper or silver to gold, it's to harden it, so you can't bend it in your hands.


How can you separate the mixture of sulphur power and iron fillings?

You can use a magnet to separate the iron fillings from the sulfur powder. The iron fillings will be attracted to the magnet, allowing you to easily separate them from the sulfur powder.


How would you separate gold from a mixture of gold and copper filings?

One method to separate gold from a mixture of gold and copper filings is by using a process called gravity separation. This involves shaking the mixture in water to allow the gold, being denser, to settle to the bottom while the lighter copper filings float on top. The separated gold can then be carefully collected and dried.


What method could you use to separate a mixture of iron fillings into sand?

One method to separate iron fillings from sand is by using a magnet. The iron fillings are attracted to the magnet and can be easily separated from the sand.
