Iron-rich sedimentary rocks are sedimentary rocks which contain 15% or more iron.However, most sedimentary rocks contain iron in varying degrees. The majority of these rocks were deposited during specific geologic time periods: The Precambrian (3800 to 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).

A mechano-chemical process called Rapid Oxidative Leach® (ROL®) is the gamechanger for miners struggling to extract copper and gold from low-grade ores.. The technology leaches 97-99 percent copper directly on-site in six to eight hours, from concentrates as low as 5 percent copper.

No. 523: Edison's Big Failure

Although channel iron deposits are typically low-grade at 53% to 57% Fe in-situ, they are composed of goethite-limonite which are hydrated iron oxide species. Ore typically contains around 8% to 12% water, and <5% SiO 2, and <3% Al 2 O 3. The hydrous iron oxides can be calcined, and the CID ore on a volatile-free basis is around 63% Fe or more.
