Iron and Manganese Ore Deposits: Mineralogy,

2020-8-18  The majority of ore deposits of both iron and manganese are of sedimentary origin. At present, high-grade iron ore deposits formed by hydrothermal and supergene enrichment of Proterozoic banded iron formations constitute the most important source for iron ores, with only some magmatic and skarn-type iron ore deposits being mined.

Iron Ore an overview ScienceDirect Topics

Iron ores (most in the form of taconite, because deposits rich in magnetite and hematite have been largely exploited) are mined, processed to remove noniron components, and smelted into metallic iron. Major sites of iron mining include South Africa, the United States, Australia, China, Russia, Japan, Ukraine, India, and Brazil.

This was the case for two specific iron-rich rare-earth bearing ore deposits in the Southern African region.

Collections: Iron, How Did They Make It? Part I, Mining

2020-9-18  Bog iron is formed when ground-water picks up iron from iron-ore deposits, where that iron is then oxidized under acidic conditions to form chunks of iron minerals (goethite, magnetite, hematite, etc.), typically in smallish chunks. Bog iron is much easier to smelt because it contains fewer impurities than iron ore in rock deposits, but the
