How Iron Was Made - Saugus Iron Works National

May 29, 2020  Bog ore is an iron-rich sedimentary rock that was harvested locally from bogs and similar bodies of water. It was also found in fields and meadows that used to be bogs. Bog ore is often considerably less than 50% iron. The rest of the rock was made up of impurities that the workers had to remove. Gabbro was used as a flux;a way to purify the ore.

Bog iron - Wikipedia

Europeans developed iron smelting from bog iron during the Pre-Roman Iron Age of the 5th/4th–1st centuries BCE, and most iron of the Viking era (late first millennium CE) came from bog iron. Humans can process bog iron with limited technology, since it does not have to be molten to remove many impurities. Due to its easy accessibility and reducibility, bog iron was commonly used for early iron production. Early metallurgistsidentified bog-iron deposits by indicators such

Hurstwic: Iron Production in the Viking Age

In some regions (particularly Sweden), iron ore, rather than bog iron, was the raw material for smelting. The ore was in the form of "red earth" (rauði), a powdery ocher.Regardless of the source, the raw materials were usually roasted to drive off moisture before being smelted.

The fold-processing of bog iron - Museum of Cultural History

Despite the fact that this bloom was rich in iron and well consolidated, it demonstrated poor forging properties when being processed. A number of fractures and cracks appeared – even after repeated fold-processing. This problem may well be associated with the quality of the Modum bog ore that was used for the extraction process.

Making Knives By Smelting Bog Iron - BLADE Magazine

Aug 04, 2021  There are different kinds of bog iron. All require the same kind of process to turn out a metal. Some types of bog iron react slightly different than others in the smelter, reducing to a smaller amount of usable material, for example. The end result is the same, however: a lump of relatively pure iron.

Encyclopedia of Greater Philadelphia Iron Production

Mar 08, 2017  The basis for charcoal-fueled iron production in southern New Jersey was limonite, better known as bog iron. This form of iron was created in a chemical reaction between the tannin-rich waters of the Pine Barrens and underlying iron rich sands and marls. The bog iron ore would rise up to the various creeks, rivers, and lakes of southern New Jersey.

The employment high in iron-ore mining was 6,972 in 1952. Bog iron At one time a flourishing iron industry was based on the bog iron ore found in the swamps of southern Michigan. The bog ore and clay-iron-stone concretions found in the Coldwater shale nearby supplied several furnaces in Union City- the first iron manufactured in Michigan.

Re: How is 'bog iron' formed?

Nov 17, 1999  Bog iron is a mineral iron ore also known as limonite. It forms under oxidizing conditions, because reduced iron (ferrous iron or Fe (II)) is soluble, whereas oxidized iron (ferric iron or Fe (III)) is insoluble. The oxidization can be entirely chemical-reduced iron is formed by iron-reducing bacteria which can derive energy from the process ...

Trying to extract bog iron : metalworking

Hi, Last weekend I fooled around in my home region and tried to extract some iron ore from a bog. I know a bit about bog iron and how I'm supposed to find it at the bottom of the bog as various sized rocky nodules. However, I tried something different by roasting iron-bearing mud. Was this a real-life process anytime in history?

How To Separate Iron Ore From Rock

Sep 18, 2020 Bog iron is formed when ground-water picks up iron from iron-ore deposits, where that iron is then oxidized under acidic conditions to form chunks of iron minerals goethite, magnetite, hematite, etc., typically in smallish chunks.

iron processing - Ores Britannica

The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe 2 O 3), which is red; magnetite (Fe 3 O 4), which is black; limonite or bog-iron ore (2Fe 2 O 3 3H 2 O), which is brown; and siderite (FeCO 3), which is pale brown. Hematite and magnetite are by far the most common types of ore.

Nov 21, 2007  The quality of the bog iron ore was primarily based on how the ore developed locally, and would vary from ore bed to ore bed. Some furnaces, such as Bergen Iron Works in Lakewood and the Batsto Works, increased the quality of their iron by mixing the local bog ore with iron imported from Europe. The process of putting a furnace in blast was a ...

The Bog Iron Industry - imhs2019

The resultant iron oxide is deposited along streams and in bogs where, mixed with mud, it accumulates and becomes bog ore (a variety of limonite). Here, then, is the first and most important material needed for an iron industry. Limestone, needed for flux, was abundant in the form of clam and oyster shells found in nearby salt water bays.
