Bog iron is a form of impure iron deposit that develops in bogs or swamps by the chemical or biochemical oxidation of iron carried in solution. In general, bog ores consist primarily of iron oxyhydroxides, commonly goethite (FeO (OH)).

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.

2021年5月16日 · What was plentiful was a source of ore called bog iron. Found in streams, along rivers and in swampy areas, the iron rich soil tinted the water reddish-orange color as shown in the image at the top of this post.

At the Norse settlement in L'Anse aux Meadows in Newfoundland, Canada, there is clear evidence that Norsemen harvested and smelted bog iron to use as the raw material for the iron rivets they fabricated to repair their ships there 1000 years ago.

2021年8月26日 · 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.

The source of the smelted iron at L’Anse aux meadows was bog iron. The type of forge used by the Norse (Photo 7) was likely crude and inefficient, but it was hot enough to melt the iron-rich source to make iron metal.

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. Width of sample from Estonia is 14 cm.

2020年1月31日 · Roasting can help drive off various non-helpful elements (and is pretty much mandatory for sulfur containing ores.) Roasting can also make it easier to grind up. You do know that forging scale is an excellent iron ore, Magnetite, and quit similar to the "black sand" the Japanese used in their tatara furnaces.

Often, two and a half tons of bog ore and nearly a half ton of charcoal were required to manufacture one ton of iron in the primitive furnace. Richer ore and a more efficient fuel in the form of coal, discovered in Pennsylvania, sounded an end to South Jersey’s iron industry.

Bog iron is a form of iron found in swamps. Bog Iron is generally found in a spring. Smelting bog iron has existed since pre-Roman times. Most iron smelted during the Viking era came from bog iron. In Russia, bog iron was the main source of iron until the sixteenth century. Iron was produced by Vikings around 1000 AD.
