Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.

best ratio is one furnace producing iron plates that is feeding one furnance that is producing steel plates. reason is simple, forget about crafting speed as it is the same for both furnances since they of the same type. so take the numbers the game is providing. iron plate 3.5 sec to craft requires 1 iron ore. steel plate 17.5 sec requires 5 ...
