Himalayan salt is a natural rock salt which can be mined from underground salt deposits in Pakistan. The main source of the salt is mined from the Khewra mine. Salt deposits were formed due to an ancient sea evaporating leaving behind salt. Over time the salt started to get trapped under layers of rock. Due to trace amounts of iron the salt has a delicate pink colour. Himalayan salt is mainly made up of Sodium Chloride just like regular table salt. Himalayan Pink Salt Co have a website which sells cooking salt, bath salt and salt lamps. They will also take bulk orders for retail shops, restaurants and other businesses.
