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
Brine mining depths of 6,000 to 10,000 feet, and contains about 300ppm iodine. All the world's bromine production is derived from brine. The majority is recovered from Dead Sea brine at plants in Israel and Jordan, where bromine is a byproduct of potash recovery. Plants in the United States ("see: Bromine production in the United States"), China, Turkmenistan, and Ukraine, recover bromine from subsurface brines. In India and Japan, bromine is recovered as a byproduct of sea salt production. The first commercial production of magnesium from seawater was recorded in 1923, when some solar salt plants around San Francisco Bay, California, extracted
