iron hydroxide in iron ore

Iron ore refers to rocks or minerals from which metallic iron is extracted for commercial use. These minerals appear dark grey to rusty red in color, and are usually rich in iron oxides. Iron occurs in these ores in the form of such chemical compounds as hematite, magnetite, siderite, limonite, or geothite.

In a large (10,403) cohort study of Minnesota iron ore (hematite) miners, they did not show any increased mortality in lung cancer. This study is of particular interest, for the radon levels in Minnesota iron ores, in contrast to most of the other iron ore mines examined, was low.

Ferrous Oxide (FeO), Iron Oxide (Spent) or Iron Sponge. Ferrous Oxide (FeO) may be formed in Oxygen-limited atmospheres, in flue gas, and from coal gas purification. Iron Oxide (Spent) or Iron Sponge is produced when Iron Ore is heated below the melting point of Iron. With further processing, they become Wrought Iron. REASON FOR CITATION

The plentiful iron pyrite, FeS 2 is not an acceptable ore because sulphur is a deleterious impurity in iron, and expensive to remove in refining. Iron is the fourth most plentiful element in the earth's crust (4.6%), but is so widely disseminated that it can be obtained only from ores in which iron has been specially concentrated.
