Production

Extracting and trading salt is an integral part of Spanish history with these activities dating back to times before the Roman Empire. As is known, salt is a mineral which occurs naturally in nature, with the mineralogical properties of crystallisation and formation. It is known as common or table salt, its chemical name is sodium chloride and its formula is NaCl

Salt is comprised of two ions (atom or other particle with electric charge), one of which is a positive sodium ion (cation) and the other which is a negative chloride ion (anion). In terms of weight, sodium represents 39% and chloride 61%. In both its natural state and after processing, salt is crystalline and cubic in shape. It is found dissolved in seawater, lakes and springs or in its pure form in salt beds

Salt is used worldwide as a raw material and its reserves are deemed inexhaustible as its main natural reservoir is ocean and sea water. It is unique in the fact that the process used for its extraction is totally ecological, exploiting natural energy sources in its industrial production, such as solar heat and wind energy.

Spanish salt products show a steady evolution over the last five years with yearly figures at nearly four million tonnes. Today in Spain, salt production covers the needs of domestic consumption and also allows us to hold a firm international position as an exporting country.

Salt production is undertaken in various provinces according to the extraction process used. In 2006 the distribution of table salt production was as follows:
