The word "salary" (= payment for work, remuneration) is derived from the Latin word "sal" (= salt).
In olden days, obtaining salt was a far more complicated and dangerous process than it is today. Salt was therefore significantly more expensive, even precious, and was worth its weight in gold. That's why salt was sometimes accepted as a means of payment. For example, Roman soldiers received parts of their pay in the form of salt, the so-called "salarium argentum" ("sal" = salt, "argentum" = silver / money, and thus effectively "salt money").
The current French word "salaire", in English "salary", bears witness to this. This etymology can also be found in the terms for remuneration / pay in other languages: "salario" in Spanish, "salário" in Portuguese etc.
Saline, Saltern, Salt Works
A saline, saltern or salt works is a facility or operation for obtaining salt, except for salt mines in which salt is extracted by miners.We distinguish primarily between:
vacuum salt works in which so-called vacuum salt (also called evaporated salt, saline salt or refined salt) is produced from saturated brine by means of evaporation; and
sea water salt works in which sea salt is obtained from sea water through evaporation.
Salt Dome, Salt Cap
A salt dome or salt cap is, in most cases, a steep formation. Tectonic forces from the earth's interior deformed the originally horizontal deposits and e.g. created a steep, roughly mushroom shape under high pressure.
Salt for Chemical Use, Electrolysis Salt
Salt for chemical use is salt of the quality from which primarily the chemical industry, by means of chloralkali electrolysis, obtains the basic chemicals chlorine, hydrogen and sodium hydroxide, which it requires for the production of plastics (e.g. PVC - polyvinyl chloride).
A salt garden is a sea water saltworks in which sea salt is obtained from sea water through evaporation.
At esco we use the term salt specialties to refer to all salt products that are not de-icing salt or winter maintenance products. Salt specialties are thus all food-grade salts and table salts, industrial salts, salts for chemical use, pharma salts, etc., regardless of whether the product is made from rock salt, vacuum salt or sea salt.
Salt pressed into tablet from is mainly used as regenerating salt for water softening.
Sea salt, sometimes also called solar salt, is obtained from so-called salt gardens through crystallization. During crystallization, the effects of the sun and wind play a major role. Sea salt also contains, in addition to sodium chloride, small quantities or traces of other substances, including potassium, magnesium and manganese salts.
Sodium chloride / NaCl, in mineralogy also called halite, occurs naturally in large quantities, in part dissolved in sea water, in part in solid form and different concentrations in numerous mineral compounds, such as sylvinite and carnallite.
During the solution mining process, fresh water is fed into a salt cap via bore holes. This dissolves the salt and the salt-saturated brine is then brought to the surface. Usually, the dissolved salt is evaporated in salt works to become vacuum salt, also called evaporated salt.
Stopes are the extraction blocks obtained between two horizons during planned extraction by boring and blasting.
