  • Banded Iron Formations Pyritic Black Shale And Gold

    Banded iron formations (BIF) are predominantly Precambrian sedimentary rocks composed of alternating layers of iron-rich minerals (commonly hematite and magnetite, but also siderite, chlorite, and grunerite) and silica-rich minerals (e.g., quartz or chert) in which the Fe content of the entire rock is at least 15 wt. . Although typically thought of as strictly Fe resources, such as in the.

  • Banded Iron: The Formation Of A Mining Mainstay Discoverer

    Feb 27, 2015 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. Outcrops of banded iron are found all over the world. In this post, we’ll take a look at how this distinctive formation come to be. First, consider the fact that almost all banded iron formation.
