Salt mining: mining part - Michigan State University

Halite salt (NaCl) can be mined in two different ways: as a solution or in dry mining (see map below). In solution mining, fresh water is injected through a pipe into deep shafts that end in the salt beds, and salty water (brine) is drawn upward and dried, to recrystallize the salt. Or, salty brine found in shallow wells can simply be pumped to the surface and dried there, to make salt. In dry ...

The world's largest underground salt mine is the Sifto Salt Mine. It produces over 7 million tons of rock salt per year using the room and pillar mining method. It is located half a kilometre under Lake Huron in Ontario, Canada. In the United Kingdom there are three mines; the largest of these is at Winsford in Cheshire, producing, on average, one million tonnes of salt per year.

Halite salt: The mineral Halite information and pictures

Underground Halite deposits are often mined by drilling wells into the salt layer, and bringing in hot water which quickly dissolves the salt into a brine. The brine is saturated with dissolved salt and is then pumped out. The brine evaporates and the remainder salt crystallizes and is harvested. Most commercially available Rock Salt is regrown from evaporated salt brine and is not the ...
