Mineral Deposits of Finland | ScienceDirect

The deposits are divided into two main groups based on their metal content: (1) deposits that are enriched in PGE (Pd + Pt > 500 ppb) and Cu (Ni/Cu < 13) (Vaara, Hietaharju, Peura-aho, and Lomalampi), and (2) deposits that are enriched in Ni (Ni/Cu > 15) and have low PGE contents (Sarvisoaivi, Ruossakero, and Hotinvaara).

The Oklo deposit (total production 14,000 tU), is famous for its fossil nuclear reactors, which operated naturally in the wet sandstone orebody about two billion years ago. Iron ore is not yet mined in Gabon, but the Bélinga iron ore deposit in NE-Gabon hosts estimated resources of ~384 Mt of high grade ore (Fe > 60% and P < 0.09%), and more

Ore genesis - Wikipedia

Iron ores are overwhelmingly derived from ancient sediments known as banded iron formations (BIFs). These sediments are composed of iron oxide minerals deposited on the sea floor. Particular environmental conditions are needed to transport enough iron in sea water to form these deposits, such as acidic and oxygen-poor atmospheres within the Proterozoic Era.

Geology, Prospecting and Exploration for Iron Ore Deposits

4/9/  · Exploitation of existing iron ore deposit is the easier part of the mining operations. The harder part is to find new ore deposits and to define their extent and the iron content (grade). Exploration is the process by which the accumulations of iron ore minerals can be found in the earth’s crust.
