Given that
We have a mixture of iron nail, water, oil, and salt.

We will first remove the iron nails by handpicking them.

Now we have oil, water, and salt left.

We can remove the oil by decantation.

Finally, we are left with the solution of salt and water.

By heating the solution we can evaporate all the water, and we will be left with salt residue.

The evaporated water is condensed and then collected.
