A mixture of sand, sawdust, and table salt can be separated using a combination of physical and chemical methods. First, the mixture can be poured into water, where the sawdust will float and the sand will sink. The sawdust can then be skimmed off the surface of the water. Next, the sand can be separated from the water by filtration. Finally, the table salt can be separated from the water by evaporation, leaving behind the salt crystals. **

To separate the mixture of coal, sand, and table salt, you can use a combination of physical and chemical methods. First, you can use a sieve to separate the larger particles of coal and sand from the smaller particles of table salt. Then, you can use a magnet to attract and remove the coal, as it is magnetic. Next, you can dissolve the table salt in water, leaving the sand behind as a residue. Finally, you can evaporate the water to obtain the pure table salt. **
