Depends on:
* mass or volume of solvent * type of salt * type of solvent * heat input * agitation of solvent

When salt is added to water, it increases the boiling point of the water, requiring it to reach a higher temperature to boil. This is because the salt disrupts the formation of water vapor molecules, which slows down the boiling process.
Adding salt to water actually increases its boiling point, so it will take longer for saltwater to boil compared to plain water. It is not recommended to add salt solely to make the water boil faster.
Salt water will boil at 108 degrees Celsius, so getting it to the boil will take 8% longer under the exact same circumstances as when you heat it to 100 degrees. How much time it will take in minutes depends on how high you will turn up the fire, if you will put a lid on the pan, whether you turn up or down the heat halfway etcetera.
Boil the water (and condense it if you want to keep it) and the salt will be left behind
it take more than 30 min. to boil
Water with salt will actually take longer than water without salt to evaporate. This is due to boiling point elevation. If you put a solute into water, it will make it more difficult to boil, and therefore will boil at a higher temperature. Since it takes longer for the salt water to boil, it will take longer for it to evaporate as well

Salt (or anything dissolved into water) will increase the boiling point of water. It will take longer to come to a boil. Salt reduces the vapor pressure of the water and so requires a higher energy level to boil.
Desalination (to desalinate) means to take out the salt. If you boil salt water, the water turns to gas and leaves the salt behind.
