Iron ore - Wikipedia

Iron ore being unloaded at docks in Toledo, Ohio. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH),

Underground Mining Methods

Ore does not properly exist until it has been labeled as such. To name a mineral prospect an ore body requires more information than needed to establish metal grades. Sufficient knowledge of the mineral deposit, mining technology, processing methods, and costs is needed for undertaking a feasibility study and proving the

Industrial Foregoing | Skyfactory 4 Wiki | Fandom

Industrial Foregoing is a mod that adds many machines to the game which serve a wide variety of purposes. These machines largely help the player to automate processes which are difficult or impossible to automate in vanilla Minecraft such as lava production, crop farming, animal husbandry, and ore collection. This guide is organized in a very similar way to the Industrial
