Why you able to separate the salt from the salt water solution?

Dont get me wrong, but you seem to be asking how to separate salt from water. I think if you evaporate water, the salt cannot evaporate, and it stays behind. However, if the light is really hot, it will evaporate the salt along with the water. (Example: If you put salt and water in a dish and hold it on top of a lit candle, the light is hot enough to evaporate water, but not hot enough to evaporate salt.
