Khewra Salt

What is Khewra salt?

Khewra salt is natural halite mined from underground tunnels at Khewra Salt Mine in Jhelum District, Punjab. Search queries for "khewra salt" and "pink salt khewra" usually refer to the same rock salt deposit, especially the pink-tinted layers sold domestically and abroad as Himalayan pink salt.

Retail products often use the label Himalayan pink salt. Khewra is a primary Pakistani source of this rock salt, though similar deposits exist across the Salt Range. The colour is geological, not added during processing.

This page covers formation, mining, and product types. It does not discuss health or medical uses. For the mine profile see Khewra Salt Mine. For history see mine history.

How pink rock salt formed in the Salt Range

The Salt Range formed when ancient seabeds were buried and compressed during the Himalayan orogeny, the collision of the Indian and Eurasian tectonic plates. Evaporated seawater left thick halite layers that were later folded and thrust upward.

Khewra sits on a salt dome where halite rose close to the surface. Pink, white, and reddish bands in tunnel walls reflect variations in trace mineral content, mainly iron oxide. Colour variation does not change the basic chemistry: it remains rock salt.

The Geological Survey of Pakistan has published Salt Range bulletins mapping these strata. Similar halite deposits appear at other sites in the range, but Khewra's tunnel network is the most developed in Pakistan.

Why Khewra salt has different colours

Pink and reddish tones come from iron oxide traces embedded in halite crystals during geological formation. White bands in the same tunnel wall are chemically similar halite with fewer colour-causing minerals.

Miners and processors sort salt partly by colour for market preference. Edible pink salt is washed, dried, and graded. Decorative lamp blocks are chosen for size, colour intensity, and carving quality rather than chemistry alone.

Colour alone is not a reliable indicator of mineral composition without laboratory analysis. This website does not make claims about purity, nutrition, or therapeutic properties.

How rock salt is mined at Khewra

PMDC uses room-and-pillar mining at Khewra. Miners cut chambers and leave salt pillars to support the roof. Extracted rock is hauled to surface processing plants near the mine entrance.

Pink, white, and industrial grades are crushed, screened, and bagged for different markets. Tourist tunnels show the same salt layers visitors see in gift-shop products, though industrial output comes from active levels not open to the public.

If your search is for a pink salt mine as a place rather than a product, read pink salt mine at Khewra. For a chamber-by-chamber description of the tourist route, see inside the mine. For production overview, see ecosystem and mining.

Khewra salt and the Himalayan pink salt label

Retail products often use the name Himalayan pink salt even when the rock is mined in Pakistan's Salt Range. Khewra is a primary domestic source of this halite, exported and repackaged under many brand names abroad.

The label describes a geological product type (pink rock salt from the Himalayan foreland), not a single mine brand. Khewra's pink layers come from the same ancient evaporite deposits described in Geological Survey of Pakistan Salt Range bulletins.

This page covers geology, mining, and product types only. For salt varieties sold at the mine, see products and salt types.

Pink, white, reddish, and kala namak

Edible pink rock salt is the best-known retail product. White industrial salt goes to chemical plants, water treatment, and road de-icing. Decorative items include salt lamps, candle holders, bricks, and tiles.

Kala namak (black salt) is processed from Khewra rock salt heated with spices. The sulphurous aroma and dark colour come from that process, not from a separate black rock layer in the mine.

The gift shop at the mine entrance sells smaller quantities for tourists. Bulk orders go through PMDC commercial channels. Global supermarket brands often buy Pakistani rock salt and repackage it abroad.

• Himalayan pink rock salt (edible, export and domestic)
• White industrial salt (chemical and road use)
• Kala namak / black salt (processed product)
• Salt lamps, bricks, and decorative blocks
• Spa and construction-grade salt crystals

Himalayan salt lamps from Khewra, Pakistan

US and European shoppers often search for Himalayan salt lamps from Khewra or Pakistan. Most retail lamps are carved from pink halite blocks sorted at Khewra processing plants. The Himalayan name on the box describes the geological region (the Himalayan foreland and Salt Range), not a single brand or mine trademark.

Lamp blocks are chosen for size, colour, and carving quality. Wiring and bulbs are added at workshops in Pakistan or in import countries. A lamp bought in New York or London may still trace back to Salt Range rock salt even when the label only says Himalayan pink salt.

Visitors can see raw pink salt walls in tourist tunnels and buy smaller lamps at the gift shop near the mine gate. Bulk export moves through PMDC commercial channels. This page does not compare lamp brands or claim air-quality benefits.

Khewra salt vs visiting Khewra Salt Mine

Searching khewra salt usually means the mineral product. Searching khewra salt mine usually means the tourist attraction. They share the same geological deposit but serve different needs.

Product questions (colour, lamps, export) belong on this page. Trip questions (hours, train ride, directions) belong on Khewra Salt Mine, visitor hub, and location. The plural name Khewra mines covers the wider PMDC complex.

Historical importance of Khewra rock salt

Salt from the Salt Range supplied Punjab kitchens and preservation needs for centuries before modern industry. Trade routes crossed these hills long before British engineers mapped the Khewra dome in 1872.

Under colonial administration, rail links moved salt to Punjab markets at industrial scale. After independence, PMDC made Khewra a cornerstone of Pakistan's domestic rock salt supply.

Pink salt's global retail popularity grew in recent decades, but the geological deposit itself is ancient. Khewra's role is extraction and primary processing, not the global branding seen on foreign supermarket shelves.

Where Khewra salt goes after the mine

PMDC sorts salt by crystal size, colour intensity, and intended use after crushing. Fine grains go to table salt packs. Larger crystals become lamp blocks or industrial bulk bags.

Export buyers specify mesh size and moisture content. Food-grade batches pass hygiene checks before shipment. Industrial grades skip those steps and ship in bulk.
