Title: History of salt
Content:  Salt comes from two main sources: sea water and the sodium chloride mineral halite (also known as rock salt). Rock salt occurs in vast beds of sedimentary evaporite minerals that result from the drying up of enclosed lakes, playas, and seas. Salt beds may be up to 350 m thick and underlie broad areas. In the United States and Canada extensive underground beds extend from the Appalachian basin of western New York through parts of Ontario and under much of the Michigan basin. Other deposits are in Texas, Ohio, Kansas, New Mexico, Nova Scotia, and Saskatchewan. In the United Kingdom underground beds are found in Cheshire and around Droitwich. Salzburg, Austria, was named "the city of salt" for its mines. High-quality rock salt was cut in medieval Transylvania, Maramureş and Southern Poland (Wieliczka). Tuzla in Bosnia and Herzegovina was named in Hungarian Só (salt) from the twelfth century on and later "place of salt" by Turks. Salt is extracted from underground beds either by mining or by solution mining using water to dissolve the salt. In solution mining the salt reaches the surface as brine, from which the water is evaporated leaving salt crystals.
Title: Brine mining
Content:  Salt (sodium chloride) has been a valuable commodity since prehistoric times, and its extraction from seawater also goes back to prehistory. Salt is extracted from seawater in many countries around the world, but the majority of salt put on the market today is mined from solid evaporite deposits. Salt is produced as a byproduct of potash extraction from Dead Sea brine at one plant in Israel (Dead Sea Works), and another in Jordan (Arab Salt Works). The total salt precipitated in solar evaporation at the Dead Sea plants is tens of millions of tons annually, but very little of the salt is marketed. Today, salt from groundwater brines is generally a byproduct of the process of extracting other dissolved substances from brines and constitutes only a small part of world salt production. In the United States, salt is recovered from surface brine at the Great Salt Lake, Utah, and from a shallow subsurface brine at Searles Lake, California.
Title: Livingston County, New York
Content:  Salt was discovered more than 1000 feet below the surface in Livingston County in the early 1880s. Salt mines opened in the towns of Leicester (Cuylerville), Livonia, Mount Morris, and York (Retsof). The Retsof mine became the largest salt-producing mine in the United States and the second largest in the world. The industry was a major employer throughout most of the 20th century until the mine collapsed and flooded in 1994. American Rock Salt opened a new mine in 1997 at Hampton Corners in the Town of Groveland and soon afterwards became the largest operating salt mine in the U.S.
Title: Salt well
Content:  A salt well (or brine well) is used to mine salt from caverns or deposits. Water is used as a solution to dissolve the salt or halite deposits so that they can be extracted by pipe to an evaporation process, which results in a brine or dry product for sale or use. In the United States during the 19th century, salt wells were a significant source of income for operators and the government. Locating underground salt deposits was usually based on locations of existing salt springs. In mountainous areas, a similar technique called sink works (from German sinkwerk) is used.
Title: Compass Minerals
Content:  Underground salt mining produces rock salt using both drill-and-blast and continuous mining techniques in deep deposits. Compass Minerals is the largest rock salt producer in North America and the U.K. It operates underground salt mines at Goderich, Ontario, the largest salt mine in the world with an annual capacity of 9 million tons; Cote Blanche, Louisiana, with annual capacity of 3.4 million tons; and Winsford, Cheshire, United Kingdom, with annual capacity of 1.5 million tons.
Title: Sodium chloride
Content:  Salt is currently mass-produced by evaporation of seawater or brine from brine wells and salt lakes. Mining of rock salt is also a major source. China is the world's main supplier of salt. In 2017, world production was estimated at 280 million tonnes, the top five producers (in million tonnes) being China (68.0), United States (43.0), India (26.0), Germany (13.0), and Canada (13.0). Salt is also a byproduct of potassium mining.
Title: Salt in Cheshire
Content:  The manufacture of white salt for food and allied industries is now concentrated in Middlewich, in the manufacturer, British Salt, who sell under the name Saxa, and also through third parties e.g. supermarket own brands. Salt produced by British Salt in Middlewich has 57% of the UK market for salt used in cooking. The UK's largest rock salt (halite) mine is at Winsford. It is one of only three places where rock salt is commercially mined in the UK, the others being at Boulby Mine, North Yorkshire and Kilroot near Carrickfergus, Northern Ireland. Rock salt extraction began at Winsford in the 17th century. Initially it was used only as salt licks for animals, and to strengthen weak brine. In 1844 Winsford Rock Salt Mine was opened, and is claimed by its operator, Salt Union Ltd., to be "Britain's oldest working mine".
Title: Brine mining
Content:  In 1997 about two-thirds of world sodium sulfate production was recovered from brine. Two plants in the US, at Searles Lake, California, and Seagraves, Texas, recovered sodium sulfate from shallow brines beneath dry lakes.
Title: Salt pan (geology)
Content:  The Bonneville Salt Flats in Utah, where many land speed records have been set, are a well-known salt pan in the arid regions of the western United States. The Etosha pan, in the Etosha National Park in Namibia, is another prominent example of a salt pan. The Salar de Uyuni in Bolivia is the largest salt pan in the world. It contains 50% to 70% of the world's known lithium reserves. The large area, clear skies, and exceptional flatness of the surface make the Salar an ideal object for calibrating the altimeters of Earth observation satellites. Parts of Rann of Kutch (India) are salt marsh in summer and salt pan in winter.
Title: Strataca
Content:  Because of the impurities (mostly shale and anhydrite), rock salt is used primarily as road salt. The method of producing rock salt has changed significantly over the years from men hacking at the salt-face with pick-axes to a highly efficient, modern industry. Every step of the journey that salt makes from the mine to the finished product is modern, mechanized, and efficient. Another form of mining, solution mining or the evaporation process, is performed at Cargill Salt and Morton Salt, both located in Reno County. Water is forced down a pipe into the salt deposit where it dissolves into brine which is pumped
