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.
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.
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.
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.
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
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.

A copper-gold alloy hasn't chemical bondings.

use a magnet
It is not a solution !

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.
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.
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.
