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.

Which device is used to separate iron dust and sulfur?
magnet is used to seperate iron dust and sulfur dust mixture
How would you separate a mixture of iron dust and zinc dust?
First you can use a magnet to get out the iron filings. Second you could possibly separate the magnesium sulphate from fine sand and zinc powder by using a filter And finally, Magnesium sulphate dissolves in water while zinc powder is insoluble, so you could use that.
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.
Is air hetero or homo mixture?

How do you separate copper from sand dust?
You could sift the mixture through a wire screen sieve which has a mesh small enough to let the sand pass through, leaving the copper on top of the screen.
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 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 tea dust from tea?
I would use a fine meshed sieve.
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.
Dust particles in the air is an example of what type of mixture?
There's no set formula for 'dust'. It depends on what kind of dust it is.
