Beads made from meteoric iron in 3500 BC or earlier were found in Gerzah, Egypt by G.A. Wainwright. The beads contain 7.5% nickel, which is a signature of meteoric origin since iron found in the Earth's crust generally has only minuscule nickel impurities.

Mineral deposit Rainwater | Britannica
Mineral deposit Mineral deposit Rainwater: Each of the deposit-forming processes discussed above involves the transport and deposition of ore minerals from solution. But solutions can also form deposits by dissolving and removing valueless material, leaving a residuum of less-soluble ore minerals. Deposits developed as residues from dissolution are called residual deposits. They occur most
Iron ore and ochre mines | Minerals and mines
Iron ore is most commonly found as haematite (Fe 2 O 3), pyrite (FeS 2) and goethite (FeO.OH), or as a mixture of hydrated iron oxides known as limonite.In the Mendips, haematite and goethite commonly occur together as either massive, granular, often siliceous masses, or as altered, amorphous, loosely compacted, earthy varieties known as ochre.
ore | National Geographic Society
Ore is a deposit in Earth’s crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire. Copper is also used in construction.
Sedimentary Mineral Deposits Mineral Processing &
