Why is iron present in water?
The main naturally occurring iron
minerals are magnetite, hematite, goethite and siderite. Weathering processes
release the element into waters. Both mineral water and drinking water contain
iron carbonate. In deep sea areas the water often contains iron fragments the
size of a fist, manganese
and small amounts of lime, silicon
dioxide and organic compounds.
Iron is applied worldwide for commercial purposes, and is produced in amounts of 500 million tons annually. Some 300 million tons are recycled. The main reason is that iron is applicable in more areas than possibly any other metal. Alloys decrease corrosivity of the metal. Steel producers add various amounts of carbon. Iron alloys are eventually processed to containers, cars, laundry machines, bridges, buildings, and even small springs. Iron compounds are applied as pigments in glass and email production, or are processed to pharmaceutics, chemicals, iron fertilizers, or pesticides. These are also applied in wood impregnation and photography.
Aluminum waste products containing iron were discharged on surface water in the earlier days. Today, these are removed and applied as soil fillers.
Iron compounds are applied in precipitation reactions, to remove compounds from water in water purification processes. The 59Fe isotope is applied in medical research and nuclear physics.
