Rock Salt: The Real Diamond in a Mine

All salt around the world has the same type of composition, sodium chloride. The most natural and unprocessed one is the rock salt. However, just because all salts are made up from the same elements doesn’t mean they are all the same. Sea salt for example, has additional minerals like zinc and potassium but is also extracted from today’s seas that are polluted. Most of us are only familiar with table salt. This comes in the form of white crystals. We do not realize that it is highly processed. The many other types of salt aren’t nearly as common as table salt.  Knowing about these uncommon types of salt, and trying them out, can greatly benefit our body. This can lead us to a more healthy lifestyle.

What is Rock Salt?

Halite, also known as rock salt, often come in the form of isometric colourless crystals, but can also appear in colours ranging from grey to pink. It depends on the type of mineral impurities it contains when harvested. Rock salt was formed in the Middle Miocene Era, back to a time when there was no pollution. Formed naturally underground, it contains natural minerals in it, and is completely unprocessed. This salt is one of best salts since there isn’t much processing done during mining and it preserves all its natural components as well.

Rock Salt for Salt Therapy

 

Rock salt only has two collection processes: mining and evaporated brine (a concentrated salt solution). Back in the day, mining was a very expensive and dangerous operation because of rapid dehydration the miners suffered with the constant contact of the salt both in the mining passages and the salt microscopically in the air. Thanks to modern technology, it is now very easy to excerpt the salt from the layers of rock with the help of machines. Occasionally, there are even open cast mines, meaning the salt is mined on the surface. With evaporated brine, water is implanted into the rocks. From there, the concentrated salt solution makes its way to a collection tank through pipes and goes under a re-crystallization process. This method is not recommended since numerous minerals are lost through this process, taking away the uniqueness of rock salt.

Salt Comes in Colours

As previously mentioned, rock salt can come in a variety of colours. The different types of colours usually depend on geographical location. For example, a type of rock salt that is becoming more familiarized is pink Himalayan salt. The pink colour is formed from a higher content in iron oxide. This salt is used for salt lamps and decoration. It also works well with cooking since pink salt possess a rich mineral flavor.

Grey salt is another common type of rock salt. It can be found in underground caves in Europe, and even some in the United States and Canada. Grey rock salt is very healthy as well and comes with an additional benefit. This type of salt is used for centuries in salt therapy. The salt and the natural minerals it contains have a synergistic effect on the respiratory system. This helps in freeing the airways and allowing easier breathing. This is accomplished by using a salt machine that creates the salty aerosol for breathing. Home salt therapy is safe and effective in strengthening the respiratory system immunity.

The regular mined rock salt is just one of the many types of salt offered out there. However, this natural salt with its additional minerals make it the healthier option to use. You can use it when cooking and in therapeutic procedures like salt therapy. Once you try this salt, table salt just won’t taste the same as before.
