Features - March 2019 High levels of metal ions such as calcium and magnesium in hard water have a powerful influence on chemical processes and the performance of many products. Removing metal ions is therefore a key part of many industrial and domestic processes that use water.
Vanadium | chemical element | Britannica
Vanadium metal, sheet, strip, foil, bar, wire, and tubing have found use in high-temperature service, in the chemical industry, and in bonding other metals.Because the major commercial use of vanadium is in steel and cast iron, to which it lends ductility and shock resistance, most of the vanadium produced is used with iron as ferrovanadium (about 85 percent vanadium) in making vanadium steels.

At the venting orifice at the seafloor, mineralization of metal sulfide chimney structures occurs, templated over a matrix of anhydrite (calcium sulfate) (). Chimney deposits form rapidly, on the order of days to weeks ( 210 ), although the longevity of individual chimney structures varies over a range of timescales, with some vent structures estimated at thousands of years old ( 175 ).
