Title: Halite
Content:  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.
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: 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: 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: Salinas Grandes mine
Content:  The Salinas Grandes mine is one of the largest lithium mines in Argentina. The mine is located in northern Argentina in Jujuy Province. The Salinas Grandes mine has reserves amounting to 20 million tonnes of lithium ore grading 1.2% lithium thus resulting 293,000 tonnes of lithium.
Title: Salt Range coal mine
Content:  The Salt Range Coal Mine is a coal mine located in Punjab. The mine has coal reserves amounting to 213 million tonnes of coking coal, one of the largest coal reserves in Asia and the world.
Title: Jhelum District
Content:  The Khewra Salt Mine (or Mayo Salt Mine) is located in Khewra, north of Pind Dadan Khan, an administrative subdivision of Jhelum District, which rises from the Indo-Gangetic Plain. It is Pakistan's largest and oldest salt mine and the world's second largest. It is a major tourist attraction, drawing up to 40,000 visitors a year. Its history dates back to its discovery by Alexander's troops in 320 BC, but it started trading in the Mughal era. The main tunnel at ground level was developed by Dr. H. Warth, a mining engineer, in 1872 during British rule. After independence, the Pakistan Mineral Development Corporation took over the mine, which still remains the largest source of salt in the country, producing more than 350,000 tons per annum of about 99% pure halite. Estimates of the reserves of salt in the mine vary from 82 million tons to 600 million tons.
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: Winsford
Content:  The United Kingdom's largest rock salt (halite) mine is at Winsford. It is one of only three places where rock salt is commercially mined in the United Kingdom, the others being at Boulby Mine, North Yorkshire, and Kilroot, near Carrickfergus, Northern Ireland. Rock salt was laid down in this part of North West England 220 million years ago, during the Triassic geological period. Seawater moved inland from an open sea, creating a chain of shallow salt lakes across what is today the Cheshire Basin. As the lakes evaporated, deep deposits of rock salt were formed. Extraction began at Winsford in the 17th century. At first 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, 
Title: Winsford
Content:  Union Ltd., to be "Britain's oldest working mine". Salt Union Ltd. is part of the US-owned group of companies Compass Minerals. Today, rock salt is quarried from a depth of more than 150 metres, producing salt (commonly known as "grit") for use as a de-icing agent on roads. The mine produces one million tonnes of rock salt annually, and has a network of over 160 mi of tunnels over several square miles underneath the area between Winsford and Northwich. A worked-out part of the mine is operated by DeepStore Ltd., a records management company offering a secure storage facility. Confidential government files, hospital patient records, historic archives belonging to The National Archives, and business data are stored in the mine, where the dry and stable atmosphere provides ideal conditions for long-term document storage.
