Usually be melting the ores and adding limestone to the mix to gather the impurities which rise to the surface of the container. The impurities are then skimmed off.
Iron mainly comes from iron oxide ores, though less common ores such as the sulphide are used as available. There are usually many contaminants, such as silicon and phosphorous that need be removed by the refining process.
Ores.
Examples are: iron, copper, zinc, tin, uranium, thorium, magnesium, manganese, lithium, etc.
By smelting iron ores in the furnace, you'll earn iron ingots. Iron ores can be obtained by mining in generated caves.
Iron is usually separated from its ores through a process called smelting, which involves heating the ore with a reducing agent such as coke. This process removes the oxygen from the ore, leaving behind the pure iron metal. The impurities in the ore combine with the flux to form a slag that is then removed.

The mining of manganiferous ores valued chiefly for their iron content is classified in SIC 1011: Iron Ores
1 iron, 2 coal ores.
Iron ores that are found native include magnetite, hematite, limonite, and siderite. These ores are typically found in a pure form in nature and do not require any extraction process to obtain iron.
how the iron ores are forming
By smelting.
yes......however there are better examples of iron ores but ilmenite and rutile ARE iron ores.
