Brine extraction is the process of obtaining salt-rich water, known as brine, from underground sources or saltwater bodies. This brine is often used in various industries, including food preservation, chemical production, and de-icing roads. The extraction can be done through methods like drilling wells or evaporating seawater. Once extracted, the brine can be processed to separate the salt and other minerals. This is commonly done through evaporation techniques or reverse osmosis. The resulting products can include table salt, sodium chloride, and other valuable minerals like potassium and magnesium.
