Sinkworks
Sink works or sinkworks (from German ''Sinkwerke'') is a method of salt mining from salt deposits in mountainous areas. It is similar to brine wells in that salt was extracted by dissolving it in water. Both approaches simulate natural brine springs. It is one of the earliest methods of salt extraction from salt domes. A ''sinkwerk'' is a chamber in a salt mine filled with water to dissolve salt. The resulting brine is then pumped via brine pipelines to saltworks. This approach is commonly used when salt deposits are heavily contaminated (or, alternatively, when salt content in the deposit is low), so that mining of rock salt is not feasible. This method is common in most salt mines in Alps, where the saltrock-mudrock-tectonite known as ''Haselgebirge'' is widespread, with average halite Halite (), commonly known as rock salt, is a type of salt, the mineral (natural) form of sodium chloride ( Na Cl). Halite forms isometric crystals. The mineral is typically colorless or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salt Mining
Salt mining extracts natural salt deposits from underground. The mined salt is usually in the form of halite (commonly known as rock salt), and extracted from evaporite formations. History Before the advent of the modern internal combustion engine and earth-moving equipment, mining salt was one of the most expensive and dangerous of operations because of rapid dehydration caused by constant contact with the salt (both in the mine passages and scattered in the air as salt dust) and of other problems caused by accidental excessive sodium intake. Salt is now plentiful, but until the Industrial Revolution, it was difficult to come by, and salt was often mined by slaves or prisoners. Life expectancy for the miners was low. Ancient China was among the earliest civilizations in the world with cultivation and trade in mined salt. They first discovered natural gas when they excavated rock salt. The Chinese writer, poet, and politician Zhang Hua of the Jin dynasty wrote in his book ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brine Well
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. History The Chinese have been using brine wells and a form of salt solution mining as part of their civilization for more than 2000 years. The first recorded salt well in China was dug in the Sichuan province around 2,250 years ago. This was the first time that ancient water well technology was applied successfully for the exploitation of salt, and marked the beginning of Sichuan’s salt drilling industry. Sh ...

Brine Spring
A brine spring or salt spring is a Brine, saltwater Spring (hydrology), spring. Brine springs are not necessarily associated with halite deposits in the immediate vicinity. They may occur at valley bottoms made of clay and gravel which became soggy with brine seeped downslope from the valley sides. Historically, brine springs have been early sources of U.S. salt production, as in the case of the salterns in Syracuse, New York and at the Illinois Salines.

Salt Dome
A salt dome is a type of structural dome formed when salt (or other evaporite minerals) intrudes into overlying rocks in a process known as diapirism. Salt domes can have unique surface and subsurface structures, and they can be discovered using techniques such as seismic reflection. They are important in petroleum geology as they can function as petroleum traps. Formation Stratigraphically, salt basins developed periodically from the Proterozoic to the Neogene. The formation of a salt dome begins with the deposition of salt in a restricted basin. In these basins, the outflow of water exceeds inflow. More concretely, the basin loses water through evaporation, resulting in the precipitation and deposition of salt. While the rate of sedimentation of salt is significantly larger than the rate of sedimentation of clastics, it is recognized that a single evaporation event is rarely enough to produce the vast quantities of salt needed to form a layer thick enough for the formation ...

Meyers Konversations-Lexikon
' or ' was a major encyclopedia in the German language that existed in various editions, and by several titles, from 1839 to 1984, when it merged with the '. Joseph Meyer (1796–1856), who had founded the publishing house in 1826, intended to issue a universal encyclopaedia meant for a broad public: people having a general knowledge as well as businessmen, technicians and scholars, considering contemporary works like those of and to be superficial or obsolete. First edition The first part of ' ("Great encyclopaedia for the educated classes") appeared in October 1839. In contrast to its contemporaries, it contained maps and illustrations with the text. There is no indication of the planned number of volumes or a time limit for this project, but little headway had been made by the otherwise dynamic . After six years, 14 volumes had appeared, covering only one fifth of the alphabet. Another six years passed before the last (46th) volume was published. Six supplementary vol ...

Brine
Brine is a high-concentration solution of salt (NaCl) in water (H2O). In diverse contexts, ''brine'' may refer to the salt solutions ranging from about 3.5% (a typical concentration of seawater, on the lower end of that of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature). Brine forms naturally due to evaporation of ground saline water but it is also generated in the mining of sodium chloride. Brine is used for food processing and cooking (pickling and brining), for de-icing of roads and other structures, and in a number of technological processes. It is also a by-product of many industrial processes, such as desalination, so it requires wastewater treatment for proper disposal or further utilization (fresh water recovery). In nature Brines are produced in multiple ways in nature. Modification of seawater via evaporation results in the concentration of salts in the residual fluid, a characteristic geologic deposit call ...

Brine Pipeline
A brine pipeline is a pipeline to transport brine. It is a common way to transport salt from salt mines, salt wells and sink works to the places of salt evaporation (salterns, salt pans). Brine pipelines are also used in the oil and gas industries, and to remove salts and contaminants from water supplies. Salt mining Brine pipelines were originally made of hollowed wood. One of the earliest known wooden pipelines ran from Bad Reichenhall to Traunstein to Rosenheim, Germany, in 1619. An ancient brine pipeline may be traced along the Sentier du Sel, a 12.5 km trail in Chablais vaudois, Switzerland ). Swiss law does not designate a ''capital'' as such, but the federal parliament and government are installed in Bern, while other federal institutions, such as the federal courts, are in other cities (Bellinzona, Lausanne, Luzern, Neuchâtel ....

Saltworks
A saltern is an area or installation for making salt. Salterns include modern salt-making works (saltworks), as well as hypersaline waters that usually contain high concentrations of halophilic microorganisms, primarily haloarchaea but also other halophiles including algae and bacteria. Salterns usually begin with seawater as the initial source of brine but may also use natural saltwater springs and streams. The water is evaporated, usually over a series of ponds, to the point where sodium chloride and other salts precipitate out of the saturated brine, allowing pure salts to be harvested. Where complete evaporation in this fashion was not routinely achievable due to weather, salt was produced from the concentrated brine by boiling the brine. Background Earliest examples of pans used in the solution mining of salt date back to prehistoric times and the pans were made of ceramics known as briquetage. Later examples were made from lead and then iron. The change from lead to iron c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Salt
Halite (), commonly known as rock salt, is a type of salt, the mineral (natural) form of sodium chloride ( Na Cl). Halite forms isometric crystals. The mineral is typically colorless or white, but may also be light blue, dark blue, purple, pink, red, orange, yellow or gray depending on inclusion of other materials, impurities, and structural or isotopic abnormalities in the crystals. It commonly occurs with other evaporite deposit minerals such as several of the sulfates, halides, and borates. The name ''halite'' is derived from the Ancient Greek word for "salt", ἅλς (''háls''). Occurrence Halite dominantly occurs within sedimentary rocks where it has formed from the evaporation of seawater or salty lake water. Vast beds of sedimentary evaporite minerals, including halite, can result from the drying up of enclosed lakes and restricted seas. Such salt beds may be hundreds of meters thick and underlie broad areas. Halite occurs at the surface today in playas in region ...
