Form in which iron occurs naturally. Ores are primarily iron and oxygen but may include phosphorous, and ??. Before the development of the Basic Bessemer Process, only high quality ores (typically Swedish) could be used for the production of iron, as high phosphorous caused numerous problems. Typical British Ores contained ??% iron but production of these generally stopped when imported ore containing up to ??% iron became available. Ore used in the U.K. is generally imported from
the natural mineral that contains iron
A substance found in rocks and soil. It was plentiful in Batsto where it was melted down and molded into items such as cannonballs.
The primary raw material in the manufacture of steel, it contains enough iron to be a commercially viable source for steel-making. Except for fragments of meteorites found on Earth, iron is not a free element; instead, it is trapped in the earth's crust in its oxidized form.
an ore from which iron can be extracted
A solid naturally-occurring mineral aggregate from which metal may be recovered via a treatment process.
rocks or deposits containing compounds from which iron can be extracted
A mineral that contains enough iron to be a factor in stainless steel production.
Mineral containing enough iron to be a commercially viable source of the element for use in steelmaking. Except for fragments of meteorites found on Earth, iron is not a free element; instead, it is trapped in the earth's crust in its oxidized form.
Iron ores are rocks and minerals from which metallic iron can be extracted. The ores are usually rich in iron oxides and vary in colour from dark grey to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), limonite or siderite.
