What is solar salt?

Solar salt is a type of salt that is produced through the evaporation of seawater or brine in large salt pans. This process relies on the heat and energy from the sun to evaporate the water, leaving behind the salt crystals.

Solar salt is typically used for various industrial purposes, such as in the production of chemicals, as a de-icing agent, in water treatment, and in the food industry. It is also commonly used for water softening in households.

Solar salt is known for its high purity, as the evaporation process tends to remove impurities and other minerals from the salt. This makes it a popular choice for many applications where purity is important.

One of the main producers of solar salt is located in the San Francisco Bay Area, where large salt pans are used to produce millions of tons of solar salt each year.
