How do you separate sawdust from salt and sand without using water?

If the particles are each of different size, these compounds may be separated based on two selective filtrations using appropriately-sized sieves.
If this process is not possible, than separation may be accomplished by dissolving the salt in another polar solvent such as liquid ammonia or methanol (about 1 or 2 grams of NaCl will dissolve per 100mL of these solvents). The sand and sawdust could then be separated using their density, as the sawdust would float and the sand would sink. Evaporation the solvent would yield the solid salt.

∙ 13y agoI dont know but you can separate salt from water with string basicly pop the string in and wait a day and salt is ... gone! stuck to the string
sorry for not answering your question!

∙ 9y agoThere are a couple of ways that you can separate sand without water. You can superheat the mixture, or you can use a filter that is small enough for just the salt granules to pass through.

How do you separate sand salt and sawdust into pure states?
If all three are mixed together you can separate the sawdust from the group with a Sieve filter with holes smaller than the sawdust, but larger than the sand/salt particles. You could then use another sieve, if the sand and salt particles are significantly different in size,...OR add water to the mix....the salt will dissolve into solution leaving the sand behind. Pour off the water and let it evaporate, leaving the salt behind. Put the mixture of sand, salt and sawdust into a quantity of water: the sand will sink to the bottom, sawdust will float and salt will dissolve. Skim off (and dry) the floating sawdust. Pour off the water containing the dissolved salt. This is then heated to cause all the water to evaporate (leaving behind the salt). The remaining residue in the original container (wet sand) can now be dried off with heat.
Can you separate sugar from water using decantation?
No. You can separate sugar from water by evaporation.
What will freeze first water and sawdust or water?
Water
What does sawdust do when in water?
it sinks to the bottom
How can you separate sawdust from gravel?
Place the sawdust and gravel mixture in water and stir. Let it sit for a time - the gravel will fall to the bottom and the sawdust will float on the top. Density of gravel is greater than water and density of sawdust (wood) is less than water. The layer of sawdust can be carefully removed by skimming it off water's surface or by pouring gravel and sawdust through a series of mesh screens of varying size (the screens can be used with dry or wet mixture)I would use the difference in density of the two materials. A simple method would be to have a stream of the mixed materials poured from a higher elevation to a lower, with a stream of air blowing across the stream. Being less dense, the sawdust will be blown to one side, the gravel will drop straight down. Of course, you COULD just drop the mixed materials into water- sawdust floats, gravel does not. Sawdust will also burn, where gravel will not. Roasting the gravel at a heat above the combustion point of sawdust will cause it to ignite, burning the sawdust away, leaving gravel. Of course, if you have plenty of time, just turn a few termites loose on the mix- they will eat wood- but not gravel!
How do you separate sawdust from nails?
If the "plastic" sawdust truly is plastic, then it won't dissolve or go mushy in water. Real sawdust will.
How do you separate sawdust and pumice?
we will use some methodsto separate pumice from water we will use a magnateto separate sawdust from water we will use the method of sedimentation , to make it more clear we will use the method of filtration
How will separate the components of a mixture containing sawdust sugar and iron filings?
Use a magnet to separate the iron filings, filter the remaining sawdust and sugar water solution, evaporate the water from the sugar water solution.
How will you separate the components of a mixtures containing sawdust sugar and iron filings?

Can you separate the cornstarch from water without using filter paper?
No!
How would you separate a mixture of sand sawdust iron filings and sugar?
water and a magnet
What method do you use to separate iron filings from sawdust?
Use a magnet to seperate the iron. Then, add water to dissolve the salt and float the sawdust. Skim off, sieve or filter the solution to seperate the sawdust. Let the water evaporate, leaving the salt behind.
Explain how you can use physical properties to separate filings from sawdust?
If they are iron filings, you can use the property of magnetism to remove the iron filings using a magnet. You will need to rinse the iron filings with water after you remove them with the magnet in order to completely remove the sawdust from them.
How can you separate soil particles from a jar of water can you separate them without using any instrument?
sedimentation and decantation
How do you separate gravel and sawdust?
If you think about it, you can figure it out. Does one of the substances float in water and the other one sink?
How do you separate a mixture of pepper sugar and sawdust?
pepper actually floats only some goes to the bottom in a water solution so after that you would need to filter the pepper and sawdust because it is larger and then evaporate the water.
How could you separate sawdust and iron fillings in a solution?
you would use the iron's magnestism to extract it with a magnetic tube
