Salt Production and Processing
Salt is the common name for the substance sodium chloride NaCI , which occurs in the form of transparent cubic crystals. 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 peoples—such as the Inuit of the far north, the Bedouin of the Middle Eastern deserts, and the Masai of east Africa—use no other form of salt. As agriculture developed, leading to an increased population and a diet consisting mostly of plants, it became necessary to devise ways of obtaining salt in greater amounts.
The earliest method of salt production was the evaporation of seawater by the heat of the sun. This method was particularly suited to hot, arid regions near the ocean or near salty lakes and is still used in those areas. Solar evaporation was soon followed by the quarrying of exposed masses of rock salt, which quickly developed into the mining of underground deposits of salt.
Two thousand years ago the Chinese began using wells to reach underground pools of salt water, some of which were more than 0. In areas where the climate did not allow solar evaporation, salt water was poured on burning wood or heated rocks to boil it. The salt left behind was then scraped off. During the time of the Roman empire, shallow lead pans were used to boil salt water over open fires.
In the Middle Ages these were replaced with iron pans which were heated with coal. In the s a procedure known as the Michigan process or the grainer process was invented, in which salt water was heated by steam running through pipes immersed in the water.
This process is still used to produce certain types of salt. By the late s open pans were replaced by a series of closed pans, in a device known as a multiple-effect vacuum evaporator, which had been used in the sugar industry for about 50 years.
Salt is obtained from two sources: rock salt and brine. Rock salt is simply crystallized salt, also known as halite. It is the result of the evaporation of ancient oceans millions of years ago. Sometimes pressure from deep inside the Earth forces up large masses of rock salt to form salt domes. Brine is water containing a high concentration of salt. The most obvious source of brine is the ocean, but it can also be obtained from salty lakes such as the Dead Sea and from underground pools of salt water.
Brine may also be artificially produced by dissolving mined rock salt or by pumping water into wells drilled into rock salt. Natural brines always contain other substances dissolved along with salt. The most' common of these are magnesium chloride, magnesium sulfate, calcium sulfate, potassium chloride, magnesium bromide, and calcium carbonate. These substances may be as commercially valuable as the salt itself. Rock salt may be quite pure, or it may contain various amounts of these substances along with rocky impurities such as shale and quartz.
For table salt, however, additives are usually mixed in. Most table salt is iodized in order to provide the trace element iodine to the diet. This helps to prevent goiter, a disease of the thyroid gland. To supply iodine, a small amount of potassium iodide is added. Table salt also contains a small amount of various chemicals used to keep the salt from absorbing water and caking.
These chemicals include magnesium carbonate, calcium silicate, calcium phosphate, magnesium silicate, and calcium carbonate. 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. To test solubility, a 0. It should completely dissolve in no more than 20 minutes. Evaporated salt intended for food processing is very pure, containing as much as 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 foods become rancid.
In addition, calcium and magnesium both tend to make salt absorb more water, causing it to cake. Salt intake—or more precisely, sodium intake—is a controversial topic in health care today.
Healthy adults can safely consume 0. For some people with high blood pressure, salt intake should be reduced. About one-third to one-half of all hypertensive people are salt-sensitive and will benefit from a low-sodium 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 low-sodium diet usually aims to reduce sodium intake to less than 0. 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.

It is composed of The most familiar use of salt is as a food preservative and additive. It is an excellent carrier of iodine in the form of potassium iodide, and its widespread use in food makes it an ideal medium for the prevention of iodine deficiency disorders to which about one billion people are at risk, mainly in developing countries. Other common uses are in the leather tanning industry, commercial dye manufacturing, and in the pulp and paper industry. In cold northern hemisphere countries, large amounts of salt are used as a de-icing agent on roads.

Our Company began as a mining and manufacturing company with a salt mine in Hockley, Texas. Patillo Higgins committed the resources of his exploration and production company to explore similar surface indications to Spindletop and drilled six wells in the Hockley area. The sun and wind evaporate the water from the brine producing a high purity salt. United Salt Carlsbad, LLC then carefully washes and screens the Solar Salt before it is packaged into a variety of our Solar Salt products, including solar crystals, agricultural blocks and compacted pellets. The Baytown Evaporated Salt Plant utilizes the mechanical vapor recompression evaporation process to produce Evaporated Salt.
This is the oldest method of salt production. It has been used since salt crystals were first noticed in trapped pools of sea water. Its use is practical only in warm climates where the evaporation rate exceeds the precipitation rate, either annually or for extended periods, and ideally, where there are steady prevailing winds. Solar salt production is, typically, the capturing of salt water in shallow ponds where the sun evaporates most of the water.
Sodium chloride is not classified as dangerous to the environment and the manufacture of salt does not require registration under the Environmental Protection Act Integrated Pollution and Control Regulations. In addition, members of The Salt Association seek to minimise the environmental impact of their manufacturing, storing and distributing operations using the available technology, and pursue continuous improvement in all their activities.
