About Salt

Salt is a mineral that is composed primarily of sodium chloride and is essential for life. Salt is one of the oldest, most ubiquitous food seasonings and salting is an important method of food preservation. The taste of salt (saltiness) is one of the basic human tastes.

In human history, salt has long been considered a valuable commodity. Evidence suggests that extraction of salt by boiling salt-laden spring water dates as far back as 6050BC.
It is translucent, colourless, odourless and has a distinctive and characteristic taste.

Salt occurs naturally in many parts of the world in mineral form and has been mined for thousands of years.

The manufacture and use of salt is one of the oldest chemical industries. Salt can be obtained by evaporation of sea water, usually in shallow basins warmed by natural sunlight know as sea salt or Solar Salt. Rock salt deposits are formed by the evaporation of ancient salt lakes, and may be mined conventionally or through the injection of water. Injected water dissolves the salt, and the brine solution can be pumped to the surface where the salt is collected through evaporation.

After the raw salt is obtained, it is refined to purify it and improve its storage and handling characteristics.


Iodized salt is table salt mixed with a minute amount of various iodine-containing salts. The ingestion of iodide prevents iodine deficiency. Worldwide, iodine deficiency affects about two billion people and is the leading preventable cause of mental retardation. It also causes thyroid gland problems, including endemic goitre. In many countries, iodine deficiency is a major public health problem that can be cheaply addressed by iodization of salt. Royal Salt has worked with and been credited by UNICEF for helping Nigeria achieve 100% salt iodisation, the first country in Africa to do so. We are UNICEF partner of choice in Nigeria, and work with them on a number of projects trying to bring further benefits to the health of the Nigerian people.
