Iron Ore: Sedimentary Rock Pictures, Definition &MoreEarth'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 skyscrapers.

Nearly all of Earth's major iron ore deposits are in rocks that formed over 1.8 billion years ago. At that time Earth's oceans contained abundant dissolved iron and almost no dissolved oxygen. The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters. This oxygen immediately combined with the abundant dissolved iron to produce hematite or magnetite. These minerals deposited on the sea floor in great abundance, forming what are now known as the \\"banded iron formations.\\"The rocks are \\"banded\\"because the iron minerals deposited in alternating bands with silica and sometimes shale. The banding might have resulted from seasonal changes in organism activity.

The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the mostused metal by both tonnage and purpose.

Different Types of Iron Ore 911metallurgist There 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 steelmaking the limit for phosphorus is one hundredth of one per cent for ten per cent of iron in the orethis is the socalled Bessemer

Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times highgrade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration. Iron formation is believed to be of sedimentary origin. In Ontario three epochs of deposition are known: 1. (a) KeewatinGrenville, as in the Michipicoten and

(b) the leaching out of the silica, leaving the concentrated ore in place, as in the Mesabi and other Minnesota ranges and in Labrador.Only one deposit of the second kind has so far been found in Ontario, that at Loon Lake, east of Por

Magnetite is found in three kinds of deposits: 1. Those formed by magmatic segregationthese are to be looked for in areas of syeniteporphyry, gabbro, anorthosite, and diorite. Deposits of this class are apt to be high in phosphorus, owing to the presence of apatite. Titaniferous magnetite is found as concentrations from gabbro and anorthosite, sometimes in veinlike bodies, often in irregular masses.

Limonite, or brown ore, is to be found at the bottom of some bogs and shallow lakes, in favorable situations, where the weathering rocks have yielded iron to the water draining into these basins. The limonite accumulates so fast in some places that a lake bottom may be cropped again after a number of years, as at Radnor Forges, Quebec. Considerable deposits of limonite have been found in places where there is no standing water at present. Limonite is sometimes formed in large quantities by th
