Doctors' opinion please --Sea Salt (naturally available) and refined Table Salt - which is better for health?

I understand that when naturally available Sea Salt is refined, vital minerals like Magnesium, Calcium, etc., are also removed. And these separated minerals are used in chemical industries. The salt which remains after removal of these minerals, is powdered and used as Table Salt while cooking. Since this Table Salt is without the minerals which are essential for our human body, it leads to problems like Osteoporosis, etc. Is it true?
