LAKE
SALT (RAW). |

 |
| |
Pakistan
is one of the very few countries who has been bestowed with
all the three types of available salt in the world. Lake salt
of Pakistan is excellent in quality and the quantity available
is as much as you want. The salt lakes are located some 250
KM. from the city of Karachi. At the moment small quantity
of 500 tons is extracted from these 10 to 12 lakes on daily
basis making the yearly average production to around 150,000
tons.
Laboratory
test report of lake salt extracted from one of these lakes
is being given below for the visitors information. |

REFINED LAKE
SALT |
| |
Raw
lake salt first brought into refining unit for processing. It goes
for washing in order to remove impurities and any foreign materials
which is then passes through dryer. The dried salt later moved towards
grinding machine and the grinded salt thus obtained from the grinding
section is placed for final packing. To make it iodized, iodine is
mixed as per requirement of the buyer This
is local as well as an export oriented business. Refined salt with
its free flow properties is obtained from local salt refining units.
It is packed in consumer packing as per demand in local and international
markets. Usually it is marketed in 800 grams consumer packing, which
is marketed locally and for the international buyers the standard
packing is 50 kgs in pp bags. Refined iodized salt is also exported
in consumer packs of 500 grams.

ROCK
SALT |

Pakistan
is known for its famous salt range stretching from Kala Bagh to Jhelum
covering the districts of Mianwali, Chakwal and Jhelum in the province
of Punjab. In the province of N-W.F.P. Geological surveys have determined
the existence of 2.65 billion tons alone in this area. Reserves at
Bahadur Khel in district Kohat are estimated to be 10.54 billion tons.
Rock salt found in Pakistan is the best in the world. The purity of
the best quality of Rock salt is about 99% and levels of impurities
are also very very low.
The
quality of Rock salt as far as crystals is concerned can be found
here of four different types including pink, and white solid crystal
and the other two available are soft lump and soft crystalline lump.
The soft crystalline lump is so soft that it can be very easily broken
down to tiny crystals by ones own hands.
We give below laboratory test report of Rock Salt for visitors information:-
