How do you separate sand from water?
You just need to use filter paper. use the filter paper than just pour the water and sand on the filter paper. the sand will go to the filter paper while the water will go straight to the beaker or anything below it. That is how you separate it. To separate sand and water you could pour the mixture through a filter. The water would pass through the filter but the sand would remain on top of the filter. If you didn't need to save the water you could evaporate the water and leave the dry sand behind. Or allow the sand to settle and carefully pour off the water first. Then allow the remaining water to evaporate.
How do you separate sawdust from salt paper clips and gravel?
You canseparate them with a liquid known a sulfuric acid. (it penetrates thought almost anything) Those things that are not soluble can be removed by filters, the sawdust, sand, rocks and iron. The salt and soluble iron will need to be removed chemically. You can evaporate the water and you'll have the salt after removing any iron chemically. +++ The question didn't say anything about destroying any of the materials! Sulphuric Acid is highly corrosive and would attack the iron and sawdust at least. And your skin if you splash it on yourself. I'm not sure about the salt but it would not harm the sand (quartz, or silicon dioxide grains). You can extract the rocks by sieving the mixture; and the iron (filings I presume) with a magnet. That's a start. Now you can flood the mixture with water and let the sawdust float. Scoop it from the surface of the water, and dry it. That leaves sand and salt. Dissolve the salt, filter the brine to remove the sand; dry the sand and evaporate the brine to leave the salt. BTW I hope Dale and I were not helping someone cheat with what look suspiciously like a homework question....

What is a way to separate Salt White Sand Iron filings and Gold filings into four separate piles?
Use a magent to pick out the iron particles. Soak the remainder in water until the salt is dissolved - dry the water, leaving behind a pile of salt. Mix the rest with mercury - the gold clings to the mercury, leaving behind a pile of sand. Use cyanide to separate the gold out of the mercury and remove the mercury.
