Ore Wikipedia

The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.

What is Magnetite? (with pictures) wisegeek

Jul 30, 2019Magnetite is a type of iron oxide with natural magnetic properties. In fact, it is the most magnetic naturally occurring mineral on Earth and was once used in compasses. Its chemical name is ferrous-ferric oxide, and its chemical formula is Fe 3 O 4. This mineral occurs in nearly all igneous and metamorphic rocks,

Iron Ore Mining Artifacts

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 colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite, limonite or

The magnetite has been reduced to metallic iron (white) around its exterior, but the ulvspinel laths were not reduced, and two can be seen within the iron rim at upper left. Reduction of the magnetite by CO has formed large bubbles of CO 2 (the black cavities) that were trapped in the slag at the top of the frame when it solidified.
