Rock Salt:

The KHEWRA Salt Mine (or Mayo Salt Mine) is located in KHEWRA, north of Pind Dadan Khan, an administrative subdivision of Jhelum District, Punjab Region, Pakistan, which rises from the Indo-Gangetic Plain. It is Pakistan’s largest and oldest salt mine and the world’s second largest. Also It is a major tourist attraction, drawing up to 250,000 visitors a year.


Estimates of the total reserves of salt in the mines range from 82 million tons to 600 million tons. In raw form it contains negligible amounts of Calcium, Magnesium, Potassium, Sulphates and moisture, with Iron, Zinc, Copper, Manganese, Chromium and Lead as trace elements. Rock Salt from Khewra, also known as Himalayan salt, is red, pink, off-white or transparent. In the early years of British rule, the Khewra mine produced about 28,000 to 30,000 tons per annum; it increased to about 187,400 tons per annum for the five fiscal years ending 1946–7 and to 136,824 tons for the two years ending 1949–50

The mine’s output was reported in 2003 to be 385,000 tons of salt per annum, which amounts to almost half of Pakistan’s total production of rock salt. At that rate of output, the tunnel would be expected to last for another 350 years.

SEA SALT:

The sea salt, in Pakistan, It is produced through the evaporation of the sea water. The production of this salt is carried more than 300,000 tons per year, With the ideal conditions in the city, the purity level of salt can go up to 98% of purity at times. Depending on the season, the purity levels vary between 95% and 98%. Average rainfall in Karachi is quite low throughout the year. This helps in the production of Sea salt.

LAKE SALT:

Sakaser and Tilla Jogian are the highest peaks of Salt Range. Namal Lake, Khabikki Lake and Uchhali Lake are lakes in the Salt Range. Lake salt in Pakistan is available in excellent quality and sufficient quantities. It used to be a problem for manufacturers to extract the salt from the lakes due to the difficult routes to the lakes but now with the advancements and development of the infrastructure in Pakistan, the extraction has become easier. The lakes are located about 300 km from Karachi and the transportation is done using special desert trucks that work round the clock. Currently, a small quantity of 3,000 tons is extracted on a daily basis making the yearly average production to around 900,000 tons.
