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

PURIFICATION OF IRON ORE (BY MAGNETIC SEPARATION

Iron has been known since prehistoric times. Indians were familiar with its extraction. It may be called the king of metals. The Ore of Iron can easily be separated from Gangue by this method. Large amount of ore can be purified by this method. It has two rollers, one is magnetic roller & other one is nonmagnetic roller. When ore is dropped on the magnetic roller, it moves through conveyers

Iron processing Iron processing Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine.

Ore Washing Plant Industrial-Craft-Wiki

Smelting 9 iron ore in an electric furnace takes 3510 EU, if you macerate it first it takes 12,420 EU, (5400 Macerator + 7020 Electric Furnace), and finally it takes 157,980 EU, (5400 Macerator + 144000 Wash + 8580 Electric Furnace)! That is a 145,560 EU increase for 4 iron! If you have seemly unlimited power then it makes sense but until then the 4 extra iron might not be worth the cost.

Iron Ore Magnetic Separation

Treatment Method Determination. The magnetic iron ores found in different localities vary widely, not only in their iron content, but also in their physical structure. The ores from the various districts require, consequently, radically different treatment. In the first place, bodies of ore differ widely in crystallography. For example, the ores of the Champlain Valley are more coarsely

The Extraction of Iron Chemistry LibreTexts

Iron ore is not pure iron oxide it also contains an assortment of rocky material that would not melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the furnace decomposes the limestone to give calcium oxide. \[ CaCO_3 \rightarrow CaO + CO_2 \tag{5}\] This is an endothermic
