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.
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.
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.
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.
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.
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.

pour water in the cup, the saw dust flouts up the sand stays at the bottom

Mixing water and dust can create a muddy or sludgy mixture. The dust particles can become suspended in the water, creating a cloudy appearance. Depending on the type of dust, this mixture may settle over time, leaving sediment at the bottom.

mixture, definitely. unpolluted rainwater has water, carbonic acid (from dissolved carbon dioxide in the atmosphere), dust, and maybe other things
To separate a mixture of sand, salt, and sawdust, you can use a combination of physical separation techniques. Firstly, use a sieve to separate the sawdust from the sand. Then, dissolve the salt in water, leaving the sand behind. After the salt has dissolved, use evaporation to recover the salt, leaving the sand separated.
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.
Simple. With a magnet. The iron dust will simply be attracted to the magnet. To collect the iron dust neatly, get a plastic sandwich bag or a small plastic baggie, put the magnet inside, use it to collect the iron dust, then turn the bag inside-out and remove the magnet.
