Explanation:

A cup of mixtures of iron fillings, sand and salt is a mixture who constituents are in the same phase i.e solid.

To separate them out we use the physical properties of the substances.

First spread out the mixture uniformly over a piece of paper or on the table.
Pass a bar magnet over it.
The iron fillings will become attracted to the magnet and separate from the mixture.
then pour water into the mixture of sand and salt
the salt will dissolve since sand is made up of quartz which are highly insoluble.
separate the water solution. Evaporate to dryness and recover the salt.
the sand is left behind and dried.
