Iron Deposits – Banded Iron Formations (BIF) | Geology for ...

Aug 11, 2013 · stilpronmelane (iron, magnesium alumiosilicate) Banded iron formations are critical to our current economy as they are by far the biggest source of economic iron deposits. China and Australia are the world’s largest iron producers, and both have enormous reserves of BIFs. Smaller deposits are mined elsewhere including the USA and Canada.

Banded Iron Formation - Mining Fundamentals

Banded iron formations (BIFs) are sedimentary rocks, characterized by the presence of alternating layers of iron-rich minerals - known as magnetite - and amorphous silica-rich rocks - known as cherts. Each layer is relatively thin with varying levels of thickness, measuring from a millimeter up to several centimeters.

Obviously, banded iron formations contain iron – technically, iron oxide, or rust. If you follow mining, you also know that the banded iron formations are one of the most important sources of iron in the modern world – two of the largest producers, Australia and China, have enormous reserves of iron stored within their banded iron formations.

Banded Iron Formation - an overview | ScienceDirect Topics

Banded iron formations (BIFs) are iron ores defined as layered, bedded, or laminated stratigraphic units composed of ≥15% weight iron that often contain quartz, chert, or carbonate interlayers (James, 1954; Gross, 1980).

Banded iron formation - Wikipedia

A typical banded iron formation consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe 3 O 4) or hematite (Fe 2 O 3), alternating with bands of iron-poor shales and cherts, often red in color, of similar thickness, and containing microbands (sub-millimeter) of iron oxides.

Gold Deposits - SERC

Nov 11, 2019 · The gold deposits are a result of mineralization during the Precambrian period. The Homestake ore bodies are associated with banded iron formations and interlayered metavolcanic rocks. The schists of the Homestake Formation have experienced many stages of very tight folds. The ore bodies are central to zones of cross folding.

South Pass greenstone belt - Wikipedia

Development of the large taconite (iron ore) deposits in the 1950s led to the opening of the Atlantic City iron mine, which produced more than 90 million tons of iron ore between 1962 and 1983 from banded iron formation in the Goldman Meadows Formation. Extensive gold development took place across the entire Precambrian greenstone belt in the late 1860s to …
