Iron Ore Sedimentary Rock Pictures, Definition amp; More

ResourcesFormationUsesEarth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides hematite (Fe2O3) and magnetite (Fe3O4). These iron ores have been mined to produce almost every iron and steel object that we use today from paper clips to automobiles to the steel beams in skSee more on geologyOnline Service

Impurities in Iron OresIron Ore FormationOrigin of Iron Ore BodiesMagnetiteLimoniteSideriteThere are certain impurities that lower the value of iron ores or may even make them valueless. Sulphur in the ore goes partly into the iron and steel and makes them brittle. While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle. For steel making the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the ore; this is the so called BessemerOnline Service

Types of Ore MiningHallOfFame

Ore is rock that contains economic amounts of a particular element, e.g. gold ore, iron ore, molybdenum ore, or praseodimium ore. In contrast, rock that is not judged to contain economic quantities of an element is categorized as waste rock. The metals in ore can occur in many different minerals (compounds) in the rock.

Iron oxide copper gold ore deposits

Iron oxide copper gold (IOCG) deposits are considered to be metasomatic expressions of large crustal scale alteration events driven by intrusive activity. The deposit type was first recognised, though not named as IOCG, by discovery and study of the supergiant Olympic Dam copper gold uranium deposit (Olympic Dam mine), and South American examples.

Photos of gold ores, quartz, telluride gold ore and gold

In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite. Iron pyrite is an exceedingly common associate with gold, but it also serves as a reducing agent. Therefore whenever gold is found encased in pyrite, it is always present as free gold and not as some type of gold sulphide.
