Mix with water, the pass through a filter paper. The salt will be dissolved in the water so it will be removed with the water, leaving the iron filings and gold dust on the filter paper. Leave this to dry then separate off the iron filings using a magnet, leaving behind the gold.

How would you separate a mixture of iron dust and zinc dust?
One way to separate a mixture of iron dust and zinc dust is by using a magnet. Iron is magnetic, so you can use a magnet to attract the iron dust while leaving the zinc dust behind. Alternatively, you could dissolve the mixture in a suitable solvent where zinc will dissolve, leaving iron to settle at the bottom.
Which device is used to separate iron dust and sulfur?
A magnet can be used to separate iron dust from sulfur since iron is magnetic while sulfur is not. By passing a magnet over the mixture, the iron dust will be attracted to the magnet, leaving the sulfur behind.
How do you get gold dust out of rock dust?
To separate gold dust from rock dust, you can use a method called panning. This involves adding water to the mixture and swirling it around in a pan. Gold, being denser than rock dust, will settle to the bottom of the pan while the lighter rock dust will wash away.
How could separate the mixture of salt water and saw dust?
Add the mixture of sawdust, sand and salt to water. The sawdust will float and can be skimmed form the surface. The salt will dissolve in the water. The sand can be filtered from the mixture which remains. The salt water solution which remains can be heated and the water will evaporate leaving the salt behind.
How do you separate copper from sand dust?
One common method to separate copper from sand dust is to use a technique called "gravity separation." This involves pouring the mixture into a container of water and allowing the copper, being denser than the sand, to sink to the bottom. The sand dust can then be poured off, leaving the copper behind. Another method is to use a magnet to attract and separate any magnetic particles of copper from the sand dust.
How do you separate a mixture of sand and iron filings and gold dust?
First, place the sulfur, sand and iron filings in a plastic container. Next, use a magnet to remove the iron filings from the sulfur-sand mixture and surely,the iron filings will connect to the magnet, leaving the sulfur and sand behind.
Why a magnet is used to separate iron filings from saw dust?
because magnet has a property that can attract metals/metal particles
How will you separate a mixture of ion dust and sulphur powder?
Use a magnet.
How do you separate a mixture of sand salt chalk dust and amp iron filings.?
First remove iron filings with a magnet. That leaves sand, salt and chalk dust. Add water which dissolves the salt, and filter leaving the sand and chalk dust on the filter paper. Put that back in water and add acid to dissolve the chalk dust (CaCO3) leaving the sand as a solid. Filter to obtain the sand. The chalk dust will now be in the acid as CO2 and H2O and the Ca salt of the acid.

How do you separate dust and iron dust?
To separate dust and iron dust, you can use a method called magnetic separation. Iron dust is magnetic, so you can use a magnet to attract and separate the iron dust from the non-magnetic regular dust. Just place a magnet near the mixture, and the iron dust will be attracted to the magnet, allowing you to separate the two.
' can you separate a mixture of sand salt and sawdust'?
pour water in the cup, the saw dust flouts up the sand stays at the bottom
How do you get gold dust out of rock dust?
To separate gold dust from rock dust, you can use a method called panning. This involves adding water to the mixture and swirling it around in a pan. Gold, being denser than rock dust, will settle to the bottom of the pan while the lighter rock dust will wash away.

What physical property would be the most useful in the separation of fine saw dust and salt?
Magnetism would be the most useful physical property for separating fine saw dust and salt. However, since neither is magnetic, a process of dissolving the salt in water, filtering out the saw dust, and boiling away the water is necessary.
How do you separate tea dust from tea?
I would use a fine meshed sieve.
