Environmental impact of iron ore miningWikipedia

Introduction Iron ore. Iron ore is rock containing enough iron content, and in sufficient volume and accessibility to mining and transportation to be able to be economically mined. Iron in ore iron is most commonly found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH)·n(H 2 O)) or siderite (FeCO 3).Roughly 98% of iron ore on the global market is

30.09.2012· Instead grab some Brown or Yellow Limonite and look for Limonite veins, their composition is Brown Limonite, Yellow Limonite, Banded Iron, and Malachite which is almost 3 to 4 times richer in iron due to the fact that the first three smelt into full iron ingots instead of the nuggets Vanadium Magnetite gives you. The Malachite smelts into copper as a bonus. Switching to these veins will give

LIMONITE CRYSTALS. Oxidized sulfides, black/brown in color and nonmagnetic, often occurs with magnetite. MAGNETITE. An igneous oxide of iron, with a specific gravity of 5.2 and having an iron content of 65-70% or more. Limonite crystals, sometimes mistaken for magnetite, occurs with the magnetite and sometimes may contain gold. Vinegar will

Iron can be smelted from hematite, limonite, or magnetite, and is easiest to find in sedimentary layers (though igneous extrusive layers may contain hematite). It is comparable to bronze, but is slightly weaker (but more rigid) and has a less complicated smelting process.
