Brine Brine is used for food processing and cooking (pickling and brining), for de-icing of roads and other structures, and in a number of technological processes. It is also a by-product of many industrial processes, such as desalination, and may pose an environmental risk due to its corrosive and toxic effects, so it requires wastewater treatment for proper disposal. Saline water with relatively high concentration of salt (usually sodium chloride) occurs naturally on Earth's surface (salt lakes), crust, and within brine pools on ocean bottom. Numerous processes exist which can produce brines in nature. Modification of seawater via evaporation results in
Open-pan salt making known as white salt is made by the evaporation of brine. Brine is obtained in several ways. Wild brine streams, occurring from the natural solution of rock salt by ground water, can come to the surface as natural brine springs or can be pumped up to the surface at well, shafts or boreholes. Artificial brine is obtained through solution mining of rock salt with fresh water and is known as ‘controlled brine pumping’. A Bastard Brine used to be made by allowing fresh water to run through abandoned rock salt mines. A Salt-on-Salt process strengthens brine by dissolving rock salt,
