Spread the mixture in a pan and draw the magnet through the material, capturing and separating the iron from the salt and sawdust. Repeat until the magnet doesn't capture any more iron. If the iron is too hard to remove from the magnet, drag the magnet across the bottom of the container, moving the iron to one side without directly …

Separate Sand and Salt by Melting Point. Salt (sodium chloride) and sand (silicon dioxide) have different melting points. The melting point of salt is 1474°F (801°C), while that of sand is 3110°F (1710°C). So, if you apply heat, salt melts before sand. You can use the melting point difference to separate a mixture of sand and salt by ...
