Salt Refining. This was a large-scale salt industry developed in coastal locations, based on a combination of inland salt mining and coastal salt production. Referred to as salt refining or salt-on-salt the process it combined weak brine from seawater with mined rock salt, and evaporated the brine into a white salt.
Mining - Mining - Solution mining: Natural brine wells are the source of a large percentage of the world's bromine, lithium, and boron and lesser amounts of potash, trona (sodium carbonate), Glauber's salt (sodium sulfate), and magnesium.
