∙ 10y ago1. Rock salt (as the mineral halite) contain some impurities, depending on the source - the salt mine.
2. For the use as table salt for humans halite is refined; table salt has added potassium iodate or iodide (to assure the necessary daily intake of iodine) and an anticaking agent.

Is a rock salt a organic or a clastic or a chemical?
Rock salt is a chemical sedimentary rock.
Why would the dissolution of table salt in water be considered gray area between chemical and physical change?
Because when the salt is dissolved, the chemical makeup of the crystal changes, making it a chemical change. However, you can evaporate the water, capture all the steam, cool the steam, and then you have the salt (original chemical makeup) and the water, making it a physical change.
What you the chemical reaction used to make rock salt?
Rock salt is simply large crystals of ordinary salt (sodium chloride). It sometimes contains sand or small rocks. No chemical reaction is used to make it. It is mined from salt deposits or obtained by evaporating sea water.
What is physical processes break rocks into fragments with the same chemical makeup and characteristics as the original rock?
mechanical wearthering
How do they extract salt from rock salt?
By chemical procedures: grinding, dissolving, filtering, repeated crystallization/recrystallization processes.
