Salt

Common salt, sodium chloride, is one of the oldest and most universally traded commodities in human history, valued for food preservation, flavouring, and in the modern age, as the feedstock for chlorine and sodium chemical production. Itis recovered from halite deposits by solution mining or direct extraction, and requires only simple washing, drying, and grinding to reach food-grade or industrial-grade purity. In Oceanyka, salt production from the extensive interior evaporite deposits is a modest but stable industry, and The World's End Beacon, an ancient mega-structure wholly dedicated to the production of commercial salt, is a testament to its age.
