Iron ore mining and dressing - tec-science

Regions in which iron ore has formed over millions of years (e.g. through volcanism) and can be mined economically are also referred to as iron ore deposits. Especially many ore deposits can be found in countries such as China, Australia, Brazil, India and Russia. These countries account for around 85 % of the total global iron ore mining volume.

Iron-rich sedimentary rocks - Wikipedia

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).
