Brine rejection that drains from the newly formed ice is replaced by a weak flow of relatively fresh water, from the liquid region below it. The new water partially freezes within the pores of the ice, increasing the solidity of the ice. As sea ice ages and thickens, the initial salinity of the ice decreases due to the rejection of brine over time [Fig. 2]. While the sea ice ages, desalinization occurs to such a degree that some multiyear ice has a salinity of less than 1 PSU. This occurs in three different ways: Brine rejection occurs in the sea ice packs
Brine mining plants, in Texas and Norway, provided more than half the world's primary magnesium through the 1950s and 1960s. As of 2014, the only producer of primary magnesium metal in the United States was U.S. Magnesium LLC, which extracted the metal from surface brine of the Great Salt Lake, at its plant in Rowley, Utah. The Dead Sea Works in Israel produces magnesium as a byproduct of potash extraction. Starting in 2002, CalEnergy extracted zinc from brines at its geothermal energy plants at the Salton Sea, California. At full production, the company hoped to produce 30,000 metric tons of 99.99% pure
