Bog Iron Ore Process

Bog iron - Wikipedia

Bog iron is a form of impure iron deposit that develops in bogs or swamps by the stone or biochemical oxidation of iron carried in solution. In general, bog ores consist primarily of iron oxyhydroxides, commonly goethite (FeO(OH)).. Iron-bearing groundwater typically emerges as a spring.The iron is oxidized to ferric hydroxide upon encountering the oxidizing environment of the surface.

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.

Bog iron ore | mineral | Britannica

Bog iron ore, Iron ore consisting of hydrated iron oxide minerals such as limonite and goethite formed by precipitation of groundwater flowing into wetlands. Bacterial action contributes to formation of the ore. Economically useful deposits can regrow within 20 years after harvesting. Bog iron was

Step 2. Collecting bog iron ore. For our smelting experiments we use bog iron ore as opposed to industrial iron ore mined mainly from Banded iron formations (BIFs). The common characteristic features of bog iron ores are that they are situated close to the surface of the ground which makes them easy to …

Iron ore - Wikipedia

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil ".

Bog Iron: Iron ore

Bog iron is a type of iron ore composed of mostly mineral goethite and other iron-bearing minerals with impurities like clay or plant debris.. Bog iron is typically rust-colored and composed of limonite. It is a mixture of iron-bearing minerals, most important of them is goethite.

Iron processing - Ores | Britannica

Iron processing - Iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine.

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.

Iron Production | Encyclopedia of Greater Philadelphia

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 stone 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.

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 ...

Iron working processes - hist-met.org

iron compounds to form ore bodies. The commonest ores are limonites, carbonates and hematites. They occur as bedded or vein deposits and as nodules within other deposits eg clays. However, a major ore source in antiquity was bog iron ore, which formed by the precipitation of iron compounds in lakes and bogs. Iron smelting sites are therefore not

Iron IV - Michigan State University

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.

Where To Buy Iron Ore : Blacksmith

turning iron ore into usable metal for forging isnt that simple, you may want to research iron bloomery processes and ancient crucible steel processes. as for ore, youll likely be able to get more iron for cheaper if you can just dredge iron sand out of a creek or melt down scrap than if you have ore shipped to you. if you want to go completely traditional you may also want to research bog ...
