Extraction of salt

NACE code 08.93 covers the extraction of salt, a vital mineral resource that has been essential to human civilization for thousands of years. The salt industry plays a crucial role in the global economy, providing a key ingredient for food preservation, chemical production, and various other industrial processes. As a basic commodity, the extraction and distribution of salt remains an important economic activity across many regions and countries.

The extraction of salt is typically carried out through two main methods: rock salt mining and salt evaporation. Rock salt mining involves the excavation of salt deposits found naturally underground, often in the form of large salt domes or beds. Salt evaporation, on the other hand, utilizes the natural process of water evaporation to extract salt from saline solutions, such as seawater or brine. Both techniques require specialized equipment and infrastructure to extract, process, and refine the salt for commercial use.

The primary inputs for the salt extraction industry include the natural salt deposits or saline water sources, as well as the machinery and equipment necessary for mining, evaporation, and processing operations. This can include excavation equipment, pumps, evaporation ponds, and refining facilities. Additionally, the industry relies on a skilled workforce to operate the extraction and processing facilities.

The main output of the salt extraction industry is, of course, refined salt products. These can include various grades and types of salt, such as table salt, industrial salt, and specialty salts. The salt produced by this industry is then consumed by a wide range of other industries, including 10.84 Manufacture of condiments and seasonings, 20.13 Manufacture of other inorganic basic chemicals, and 38.32 Recovery of sorted materials, among others.
