Answer:
Separate Sand and Salt by Melting Point
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 heating the mixture above 801°C, but below 1710°C.
