About Us

There are two main sources of salt. It is harvested directly from either sea water or a natural brine, or from rock salt deposits that were formed as a result of the evaporation of former seas that left a layer of rock salt, otherwise known as halite. There are three types of salt extraction: solar evaporation, rock salt extraction, and solution mining. Each one involves a specific technology and manufacturers choose the most appropriate method depending on the particular topographical and socio-economic conditions in their area of ​​operation.

Salt producers use three basic technologies to produce salt for its myriad uses. The dry oceans buried in past geological ages have left many areas, both under land and sea, with concentrated salt sedimentary layers that can be more than fifty feet thick. Two technologies exploit these subterranean deposits: traditional shaft mining, where miners go underground to remove solid rock salt, and solution mining, where water is pumped underground to dissolve solid salt and then pumped brine that is drained to crystallize the salt. The third method extracts salt from oceans and salt lakes, and grows salt crystals just as a farmer grows crops of vegetables or grains. respectively , The products of these technologies are known as rock salt, evaporated salt (or vacuum salt), and solar (or sea) salt.

Of the three technologies, most producers around the world work in solar salt production, which is the least expensive technology available, when it is favored by a dry, windy climate. But huge amounts of rock salt are mined in large commercial mines and chemical companies use a huge amount of salt in the form of brine that never crystallizes into dry salt.

Logistics considerations greatly influence decisions to choose the location of the production facility, and these, in turn, greatly influence the size of production units and the structure of the salt industry. “States,” after all, don’t produce salt, salt producers do.

Solar evaporation is probably one of the oldest methods used to produce salt. According to this process, sea water or natural brine evaporates to saturation in open ponds, thanks to the influence of the sun and wind. Crystallization takes place in dedicated open vats as well, where the saturated brine is poured last. Once the salt crust has formed, the excess water is shaken off before harvesting. Raw salt can be further processed, including washing, drying, sieving and grading, if required and according to requirements.

Another method of salt production used is the evaporation of brine by the heat of steam in large commercial evaporators called vacuum tanks. This method produces salt of high purity, smooth in texture, and is primarily used in those applications where a higher quality salt is required.

The first part of the process is known as solution mining. Wells are drilled from several hundred to 1,000 feet deep into salt deposits. These wells are connected by lateral drilling, a recently developed technique. Once the wells are connected, the brine process begins: water is pumped down one well, salt is dissolved below, and the resulting brine is forced to the surface through the other well. Then it is pumped into large tanks for storage.

Next, the brine is pumped into vacuum troughs. These are huge vessels sealed under a vacuum three stories high. They are usually arranged in a series of three, four, or five, with each one in line under a larger void than the previous one. This series of vacuum pans operates on a very simple principle: as the pressure drops, so does the temperature at which the water boils. For example, under normal air pressure at sea level, water boils at 212 degrees Fahrenheit. But at ten thousand feet above sea level, where the air pressure is much lower, water boils at 194 degrees Fahrenheit. Vacuum pans may operate at temperatures as low as 100 degrees Fahrenheit.

In the vacuum pot process, steam is fed into the first pan. This causes the brine in the pan to boil. The steam from the boiling brine is then used to heat the brine in the second pan. The pressure in the second pan is lower, allowing the steam from boiling in the first pan to boil the brine in the second pan. The pressure is further reduced in each subsequent vessel. This allows the steam from the boiling brine in the previous pan to boil the brine in the next pan. While boiling can be done with just one pot, several successive pots produce more salt per pound of steam, allowing for greater energy efficiency.

It is a mineral consisting mainly of sodium chloride (NaCl), which is a chemical compound that belongs to a larger class of salts; Salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is found in large quantities in sea water, where it is the main mineral component. The open ocean contains about 35 grams (1.2 ounces) of solids per liter, and a salinity of 3.5%.

Salt is necessary for human life, and salt is one of the basic human tastes. Animal tissues contain more salt than plant tissues. Salt is one of the oldest and most widespread types of food seasoning, and salting is an important way to preserve food.g is an important way to preserve food.

Some of the earliest evidence of salt processing dates back to about 8,000 years ago, when people living in an area in what is now the country of Romania would boil spring water to extract the salts; Salt works in China date back to about the same period. Salt was prized by the Hebrews, Greeks, Romans, Byzantines, Hittites and Egyptians. . Salt became an important item of trade and was transported by boat across the Mediterranean, along specially built salt roads, and across the desert in camel caravans. The global scarcity and need for salt has led nations to fight a war over salt and its use to increase tax revenues. Salt is also used in religious ceremonies and has other cultural significance.
