    Iron ore Wikipedia

    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, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO

    How many furnaces can a "Electric Mining Drill" supply

    Note that stone requires 2 "ore" per "ingot" (2 stone per brick), but takes the same time to smelt as iron/copper. This means you need twice as many miners to supply the same number of furnaces producing the same quantity of output. However, stone is also mined around 23% faster.

    Production mining is further broken down into two methods, long hole and short hole. Short hole mining is similar to development mining, except that it occurs in ore. There are several different methods of long hole mining. Typically, long hole mining requires two excavations within the ore at different elevations below surface, (15 m 30 m apart). Holes are drilled between the two excavations and loaded with
