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.
What else can I help you with?
How would you separate gold dust from a mixture of iron filings and salt?
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?
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 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 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 would you separate a mixture of iron dust and zinc dust?
To separate a mixture of iron dust and zinc dust, one method is magnetic separation. Iron is attracted to a magnet, so passing a magnet over the mixture will attract the iron particles, leaving the zinc particles behind. Another method is to use a sieve or mesh to physically separate the larger iron particles from the smaller zinc particles based on size differences. Lastly, if the mixture is dissolved in a liquid, zinc dust can be separated from iron dust using a process called filtration, where the liquid is passed through a filter that traps the larger iron particles while allowing the smaller zinc particles to pass through.

How will you separate a mixture of ion dust and sulphur powder?
Use a magnet.

What you can get by mixing in water and dust?
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.

Is rain and element mixture or a compound?
mixture, definitely. unpolluted rainwater has water, carbonic acid (from dissolved carbon dioxide in the atmosphere), dust, and maybe other things
How can you separate a mixture of sand salt and sawdust?
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.
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.
Is rain water mixture or compound?
