Best Answer

Table salt is refined rock salt; shortly the process is:

- grinding of rock salt

- dissolving in water

- filtering

- purification by repeated processes of crystallization/recrystallization

- adding iodine (as potassium iodate or iodide) and an anticaking agent

Some sources of rock salt are practically pure and doesn't need to be refined.
