How do you separate chalk and salt?
Assuming you mean common salt, sodium chloride the two can be adding water which will dissolve the salt- filter to separate the chalk, wash and dry it. To recover the salt- Take the dissolved salt, carefully heat to boil off the water and then it let it cool to crystallize out the salt.
What method would you use to separate salt and powdered chalk?

How do you separate salt and marble chips?
First you mix both chalk and salt in water. From the solution that you get, you can filter the chalk out because it is non soluble in water. As for the salt, all there is to do is to just evaporate the water out.
How do you separate salt water from the mixture of chalk powder mixed in water?
Pass the mixture through filter paper. The salt water will pass through leaving the chalk behind in the filter paper.
What is a separating technique?
A separation technique is something used to separate an object from it's mixture. For example, in a bowl you have chalk, chalk dust, salt, and paperclips. You'd use magnetic attraction to get the paperclips out. Then you'd use your hands and take out the chalk. And then, you use a sifting tool and it'll separate the salt and chalk dust by itself. But, another cool way to separate those two is to put them in water. The salt will eventually sink because it's denser than water, and the chalk dust will float because it is less dense. Other techniques are, filteration, sifitng, magnetic attraction, evaporation, chromotography. Hope that helped! :D

How do you separate sand and chalk from a mixture?

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.
