This is how 800 million pounds of Khewra salt, often called Himalayan salt, is mined each year. Formed over 250 million years ago, and first mined in the 1200s, Himalayan salt is a mineral that was initially used as a food preservative. These days, it's more commonly used in bath salts, salt lamps, salt bricks, salt tiles and even medicines.
