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.

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. Salt is an important feedstock to the chloralkali branch of the chemical industry, being the cheapest and most common source of soda ash Na 2 O via the Solvay process see Limestone commodity review. Caustic soda NaOH and chlorine Cl 2 are produced by electrolysis of salt brine feedstock.
At one time almost all the salt used in commerce was produced from the evaporation of seawater, and sea salt still is a staple commodity in many maritime countries, especially where the climate is dry and the summer is long. Commercial salt is manufactured from rock salt, as well as from seawater and other natural and artificial brines. Most of the artificial brines are obtained by pumping water into underground salt beds. A considerable amount of brine itself is used directly in industrial countries. The beds of rock salt are mined or quarried by the usual excavation methods, depending on the depths and thicknesses of the deposits and on local conditions. The mined rock salt sometimes is dissolved and the salt manufactured by treatment of the brine, as described below.SEE VIDEO BY TOPIC: How are water softener salt pellets made?
The production of salt in the United States divides itself at the outset into two distinct classes:. The processes employed at the present time in the manufacture of salt by evaporation may be outlined as follows:. In this paper only the solar-evaporation processes practised in different parts of the United States will be described. In the Eastern States the solar-evaporation process is not generally employed for climatic reasons. In the Western States, particularly in California and Utah, the great bulk of the salt produced originates in the solar-evaporation process. Of the Eastern States producing salt, this process, so far as the writer is aware, is employed in New York State only. The manufacture of salt by solar evaporation began in the vicinity of Syracuse, Onondaga county, in The brine is stored in glacial gravels and was evidently formed by the circulation of ground waters, through adjacent beds of rock salt. But a small part of the evaporated salt manufactured in New York is now made by the solar, process. Its manufacture is limited to Syracuse and vicinity, where it has survived from the early days of the industry.
How to Make Salt by Solar Evaporation
With its capacity to enhance flavour and mask bitterness, combined with its relative abundance and low cost, it should come as no surprise to learn that salt is the most commonly used seasoning across the globe. Our love of salt is far from being a modern phenomenon. In fact, it has been integral to societies for many millennia, with the earliest record of salt usage dating back to before B.

HISTORY OF SALT PRODUCTION
For thousands of years salt has been a very important material: it was not just used for seasoning, but was needed much more as a preservative. Before ice boxes, fridges and finally freezers were invented, all foods from meat and fish to vegetables and even fruits had to be salted if they were to serve as long lasting provisions. Therefore, the use of salt can be traced as far back as Neolithic times. It was well known in the early civilisations of Mesopotamia and Egypt and in antiquity was already produced on a proto-industrial scale. Apparently, the people of what is now Hallstatt in Austria were the first to manufacture salt in large amounts. The production of salt, which still continues today, is indicated by the name "Hallstatt", because the german syllable "Hall-" goes back to the greek word salt. In the Hallstatt mine people already chiselled big chunks of rock salt from the walls in the 14th century BC. Between and BC, in the first Celtic era, production virtually went through the roof.

The study of the behavior of sessile droplets on solid substrates is not only associated with common everyday phenomena, such as the coffee stain effect, limescale deposits on our bathroom walls , but also very important in many applications such as purification of pharmaceuticals, de-icing of airplanes, inkjet printing and coating applications. In many of these processes, a phase change happens within the drop because of solvent evaporation, temperature changes or chemical reactions, which consequently lead to liquid to solid transitions in the droplets. Here we show that crystallization patterns of evaporating of water drops containing dissolved salts are different from the stains reported for evaporating colloidal suspensions.
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. The industry, in its various forms, is regulated through a number of European Directives that regulate operating practices, food safety and environmental performance.
