- Source: Unknown. Iron ore was first discovered by European settlers when the early land surveyor, William Austin Burt, was shown iron ore by an Indian chieftain near what is now Negaunee, Michigan, in 1844. He had noticed a strange movement of his compass needle while surveying near where the present town of Ishpeming is located.

- Conditions of a reappearance of a sea with dissolved iron at 1,900 million years ago, and later in association with Snowball Earth BIF reappeared 750 million years ago, and that is problematic to explain (see below).anded iron beds are an important commercial source of iron ore, such as the Pilbara region of Western Australia and the Animikie Group in Minnesota.

Follow BBC Earth An iron core would account for all that missing mass . The main evidence for this is the huge amount of iron in the universe around us. It is one of the ten most common elements in our galaxy, and is frequently found in meteorites. Given how much there is of it, iron is much less common at the surface of the Earth than we might expect. So the theory is that when Earth formed 4.5 billion years ago, a lot of iron worked its way down to the core. That's where most of the mass is, and it's where most of the iron must be too. Iron is a relatively dense element under normal conditions, and under the extreme pressure at the Earth's core it would be crushed to an even higher density, so an iron core would account for all that missing mass.

SIC 1011 IRON ORES Iron ore properties in the Lake Superior district were bought by steel companies, and small mines were consolidated into larger ones by the mergers of large mining companies. The structure of the iron ore industry today is a direct result of the consolidations that took place between 1893 and 1905.

History of the Iron Ore Trade The history of the trade is therefore, one of absorbing interest. Iron ore was discovered on the Marquette Range on September 19, 1844 by William A. Burt, United States Deputy Surveyor, and party who were surveying in the Upper Peninsula of Michigan.his was the first iron ever to be made from Lake Superior ore. The next step in development was the construction of a forge on Carp River, about three miles from the Jackson Mine, and on February 10, 1848, the first iron from the Lake Superior region was made in this forge by Ariel N. Berney.

- One of the first things that early colonists went after, as they tried to recreate Europe in the American wilderness, was iron. Iron ore had turned up on an island off the North Carolina coast in 1585. That was too inaccessible to mine, but then Jamestown settlers found iron ore on the mainland. In 1608, just after the Jamestown colonists came, John Smith shipped several barrels of ore back to England.

- Iron is pronounced as EYE-ern. History and Uses: Archaeological evidence suggests that people have been using iron for at least 5000 years. Iron is the cheapest and one of the most abundant of all metals, comprising nearly 5.6% of the earth's crust and nearly all of the earth's core. Iron is primarily obtained from the minerals hematite (Fe2O3) and magnetite (Fe3O4).

Timeline of chemical element discoveries The oldest known iron objects used by humans are some beads of meteoric iron, made in Egypt in about 4000 BCE. The discovery of smelting around 3000 BCE led to the start of the iron age around 1200 BCE and the prominent use of iron for tools and weapons.

History of the Iron Ore Trade History of the Iron Ore Trade. This brief history appeared in the 1910 Annual Report of the Lake Carriers' Association. The iron ore trade is, of course, the trade of the Great Lakes, but it was not always so. The premier trade for so many years was grain, then lumber took first place, giving way subsequently to coal. In fact, it was not until 1888 that iron ore became the dominant trade of the Great Lakes.

Iron Age Iron use, in smelting and forging for tools, also appears in West Africa by 1200 BC. In other regions of Europe, the Iron Age began in the 8th century BC in Central Europe and the 6th century BC in Northern Europe. The Near Eastern Iron Age is divided into two subsections, Iron I and Iron II. Iron I (1200-1000 BC) illustrates both continuity and discontinuity with the previous Late Bronze Age.

- Iron deposits near Owingsville in Bath, Powell, and Estill Counties were mined as late as the 1900's. These iron ores occur in an oolitic limestone in the Brassfield Formation of Silurian age. Specimens of limonite and hematite may also be found in this area. Iron ore was also mined in northeastern Kentucky in Greenup, Boyd, and Carter Counties, where iron ore occurs in the Upper Mississippian and Lower Pennsylvanian rocks. Siderite and limonite nodules also occur at this locality.

Iron Age Classically, the Iron Age is taken to begin in the 12th century BC in the ancient Near East, ancient Persia, ancient India (with the post-Rigvedic Vedic civilization), and ancient Greece (with the Greek Dark Ages). In other regions of Europe, it started much later. The Iron Age began in the 8th century BC in Central Europe and the 6th century BC in Northern Europe. Iron use, in smelting and forging for tools, appears in West Africa by 1200 BC, making it one of the first places for the birth of the Iron Age.

IRON ORE IRON TO STEEL. The most common industrial use of iron in modern times is steel. Approximately 98 percent of all iron ore that is mined in the world is used in the production of steel. This alloy, which is made up of mainly iron and carbon, has been used almost as long as pure iron has been used over the centuries.
