Pink salt, often referred to as Himalayan pink salt, is a type of rock salt that is mined from the Punjab region of Pakistan, specifically from the Khewra Salt Mine, which is one of the largest and oldest salt mines in the world. The pink coloration is due to the presence of trace minerals, particularly iron oxide (rust), as well as other minerals like potassium, magnesium, and calcium.

Pink salt deposits were formed millions of years ago when ancient seas evaporated, leaving behind layers of crystallized salt. Over time, geological processes and pressure transformed these deposits into rock salt.

Pink salt is mined through traditional mining methods, primarily using drilling, blasting, and excavation techniques to extract salt from deep underground deposits.

The majority of pink salt production comes from the Khewra Salt Mine in Pakistan, although other countries such as India and Nepal also have Himalayan salt deposits. These salts are marketed globally for culinary and decorative purposes.
