salt mining process

Salt mining: mining part Michigan State UniversityMining The geology of the Great Lakes salt mining area consists of sedimentary deposits of shale, limestone, sandstone, dolomite, gypsum, anhydrite, and rock salt (halite). These formations within the mining area are relatively continuous and generally undisturbed by faults or other forms of sharp ground movements.

What Is a Salt Mine? (with pictures) 18, · Mining rooms are usually created in a checkerboard pattern so that a portion of the salt, about 35 to 55 percent, is left in the form of pillars. These offer structural support for the mine. The mining process is laborintensive and begins with cutting a horizontal slot beneath a salt wall, into which blasted pieces will eventually fall.

Salt Mining HowStuffWorksIn 2006, more than 200 million tons of salt were produced in the world. China is the largest producer, with 48 million tons, followed closely by the United States, with 46 million tons [source: Salt Institute]. Salt is generally produced one of three ways: deepshaft mining, solution mining or solar evaporation.

Deepshaft mining is much like mining for any other mineral. Typically, the salt exists as deposits in ancient underground seabeds, which became buried through tectonic changes over thousands of years. Many salt mines use the \\"room and pillar\\"system of mining. Shafts are sunk down to the floor of the mine, and rooms are carefully constructed by drilling, cutting and blasting between the shafts, creating a checkerboard pattern. After the salt is removed and crushed, a conveyor belt hauls it to the surface. Most salt produced this way is used as rock salt.

When solution mines are located near chemical plants, they are called brine wells, and the salt is used for chemical production. After the salt is removed from a salt mine, the empty room often stores other substances, like natural gas or industrial wastes.

Salt is harvested through solar evaporation from seawater or salt lakes. Wind and the sun evaporate the water from shallow pools, leaving the salt behind. It is usually harvested once a year when the salt reaches a specific thickness. After harvest, the salt is washed, drained, cleaned and refined. This is the purest way to harvest salt, often resulting in nearly 100 percent sodium chloride. Only areas with low annual rainfall and high evaporation rates Mediterranean countries and Australia, for example can have successful solar evaporation plants. Usually machines perform this harvest, but in some areas it is still done by hand.

How salt is made material, used, processing, procedure Salt is the common name for the substance sodium chloride (NaCI), which occurs in the form of transparent cubic crystals. Although salt is most familiar as a food supplement, less than 5% of the salt produced in the United States is used for that purpose. About 70% is used in the chemical industry, mostly as a source of chlorine. Salt is also used for countless other purposes, such as removing snow and ice from roads, softening water, preserving food, and stabilizing soils for construction. The earliest humans obtained their salt from natural salt concentrations, called licks, and from meat. Those people who lived near the ocean may have also obtained it by chewing seaweed or from the natural evaporation of small pools of seawater. Meat became a more important source of salt as hunting was developed, as did milk when sheep, goats, horses, camels, reindeer, and cattle were domesticated. Even today, certain peoplessuch as the Inuit of the far north, the Bedouin of the Middle Eastern

Specifications for salt vary widely according to the intended use. Salt intended for human consumption must be much purer than salt used for melting snow and ice, but salt used for certain scientific purposes may need to be even purer. For most purposes, rock salt is allowed to have a gray, pink, or brown tinge rather than being pure white. The impurities that cause these colors may make up as much as 4% of a test sample. To test solubility, a 0.7ounce (20 g) sample is placed in 6.8 fluid ounces (200 ml) of water. It should completely dissolve in no more than 20 minutes. Evaporated salt intended for food processing is very pure, containing as much as 99.99% sodium chloride before additives are mixed in. This is important not only for safety and good taste, but because certain impurities can cause problems with certain foods. For example, small amounts of calcium tend to toughen vegetables. Traces of copper or iron tend to destroy vitamin C and to increase the rate at which fatty fo

Salt intakeor more precisely, sodium intakeis a controversial topic in health care today. Healthy adults can safely consume 0.20.4 ounces (611 g) of salt daily, which is equivalent to 0.080.14 ounces (24004400 mg) of sodium. For some people with high blood pressure, salt intake should be reduced. About onethird to onehalf of all hypertensive people are saltsensitive and will benefit from a lowsodium diet. Since there is no way to tell who these people are, most hypertensives under medical care will be placed on such a diet to see if it helps. A lowsodium diet usually aims to reduce sodium intake to less than 0.08 ounces (2400 mg) per day. While some have suggested that everyone should reduce salt intake, others point out that there is no evidence that salt restriction is of any benefit to otherwise healthy individuals.
