Ore Wikipedia

The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.

Ore veins are completely made up of a single type of ore poor, normal or rich. When the world generates an ore vein, it has a 20% chance to be rich, a 30% chance to be poor, and a 50% chance to be normal. One poor ore produces 15 metal units, one normal ore produces 25 metal units, and one rich ore produces 35 metal units. Veins and Clusters

Hematite Wikipedia

Hematite is colored black to steel or silver-gray, brown to reddish-brown, or red. It is mined as the main ore of iron. Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite). While these forms vary, they all have a rust-red streak. Hematite is harder than pure iron, but much more brittle.

What Is a Metal Ore?

Metal ore is a type of rock from which metal can be extracted. Metal ores are normally oxides; for example, aluminium is the most common metal in the Earth's crust, but in order to get as pure aluminium as possible, it needs to be extracted from an ore.

Sep 15, 2019Magnetite (black ore; the magnetic type of iron oxide, also called lodestone) Pyrite; Siderite; Taconite (a combination of hematite and magnetite). Different ores contain different amounts of iron. Hematite and magnetite have about 70 percent iron, limonite has about 60 percent, pyrite and siderite have 50 percent, while taconite has only 30 percent.

Types of Iron Ore Hematite vs. Magnetite MineListings

Jan 04, 2016That makes the iron extraction process much less costly and time consuming. In addition, hematite ore only goes through one stage of screening and crushing, while magnetite ore has an additional round of processing. Types of iron ore Magnetite. With the chemical formula Fe3O4, magnetite ore has much lower iron content than hematite ore.

Wisconsin Geological Natural History Survey Hematite

Botryoidal, banded, oolitic and coarsely columnar needle ore also occur. The hematite, in conjunction with other iron oxides replace iron carbonates in the ore. Associated minerals include siderite, magnetite, chamosite and stilpnomelane (U.S.G.S., 1976). A typical outcrop is near Mellen in the SW SW SE Sec. 9 T.44N R.2W (Mudrey, 1979).

Wisconsin Geological Natural History Survey Magnetite

Magnetite occurs as an accessory in most igneous, metamorphic and sedimentary rocks, where it is found as small equant, euhedral to rounded grains. It is an abundant heavy mineral in sediments and is usually the major constituent of certain metamorphosed iron formations, where it forms an important ore

THE MINERAL MAGNETITE. Magnetite is a member of the spinel group which has the standard formula A (B) 2 O 4 . The A and B represent usually different metal ions that occupy specific sites in the crystal structure. In the case of magnetite, Fe 3 O 4, the A metal is Fe 2 and the B metal is Fe 3; two different metal ions in two specific sites.

Iron Ore Statistics and Information usgs.gov

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.
