the process from digging of the iron ore from the ground

When iron making was properly established, two types of furnace came into use. Bowl furnaces were constructed by digging a small hole in the ground and arranging for air from a bellows to be introduced through a pipe or tuyere. Stone-built shaft furnaces, on the other hand, relied on natural draft, although they too sometimes used tuyeres. In both cases, smelting involved creating a bed of red-hot charcoal …

    What is Ilmenite? Ilmenite is a common accessory mineral in igneous rocks, sediments, and sedimentary rocks in many parts of the world. Apollo astronauts found abundant ilmenite in lunar rocks and the lunar regolith. Ilmenite is a black iron-titanium oxide with a chemical composition of FeTiO 3.. Ilmenite is the primary ore of titanium, a metal needed to make a variety of high-performance alloys

    heap leaching wikipedia

    Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the

    There are several ways to find iron. Many people use methods of branch mining in natural caverns or cave systems found when digging straight into the ground (that is if you are lucky.) Beginners have a good shot to find several pieces of iron ore when exploring caves (they lie on the side walls.)
