Solution
We can use a magnet to separate the iron fillings from the mixture of common salt, sand and iron fillings. Sand and salt can be separated by adding them to water, and allowing the salt to dissolve and the sand to settle. When the water is decanted, sand is left behind. By boiling the decanted water and letting it evaporate, salt can be obtained.
