1. Sieving
A mixture of sand, pebbles, and rocks can be separated by the process of sieving. Fine sand particles pass through the holes of the sieve, while bigger impurities such as stones and gravel remain on the sieve.
2. Filtration
It is easy to separate sand and water by filtering the mixture. Salt can be separated from a solution through evaporation.
3. Sieving
A mixture made of solid particles of different sizes, for example sand and gravel, can be separated by sieving. What is a sieve? An instrument with a meshed or perforated bottom, used for separating coarse from fine parts of loose matter, and for straining liquids.
4. Using a Magnet
Iron is magnetic and the other two not, which means a magnet could be used to attract the iron filings out of the mixture, leaving the salt and sand. Salt is water soluble, while sand is not. This means the two can be mixed in water and stirred. The salt will dissolve and the sand will not.
5. Using a Magnet
Pins are metal and it is attractable by magnet while assorted buttons are not.
