2O 3, % Fe), goethite ( FeO (OH), % Fe), limonite ( FeO (OH)·n (H2O), 55% Fe) or siderite ( FeCO3, % Fe). Ores containing very high quantities of hematite or magnetite, typically greater than about 60% iron, are known as natural ore or direct shipping ore, and can be fed directly into ironmaking blast furnaces.

The ore was processed by heating it by burning charcoal in simple stone furnaces. The iron ore deposits were small and difficult to exploit. When the large iron ore deposits of the Great Lakes region were discovered, iron ore was no longer mined in the eastern United States. Shown is the Vesuvius Iron Furnace of southern Ohio.

Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % to 63 % Fe) hematite iron ore. The wet process consists of multistage crushing followed by different stages of washing in the form of scrubbing and / or screening, classification etc., but the advantage is only partial removal of adhered alumina and free silica in the calibrated lump ...

By the late 1600's and early 1700's, iron ore was still being mined in ia and western Massachusetts. Small scale bloomeries, the most primitive form of smelting, reduced the ore into a porous mass of iron slag called bloom or sponge bloom was hammered into a low quality wrought iron by using hand held or large, heavy hammers powered by water.

The process begins by removing the topsoil from the area to be mined. This soil is then replaced and compacted to make sure that there is no waterlogging or runoff. The next step is to drill holes into the rock, so that explosives can be inserted. The explosives are set off, and the iron ore is blasted out of the rock.

What is Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brassyellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.
