How deep can you find iron ore? Magnetite ores. The typical grade of iron at which a magnetitebearing banded iron formation becomes economic is roughly 25% iron, which can generally yield a 33% to 40% recovery of magnetite by weight, to produce a concentrate grading in excess of 64% iron by weight.

Feb 12, · The genetic classification should ultimately determine the limits of ore deposition in each class by temperature and pressure. Each deposit should be considered as a problem in physical chemistry, and the solution of this problem, with the necessary geologic data, will suffice to fix the mode of formation of the deposit.

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. The most widely distributed ironbearing minerals are oxides, and iron ores consist mainly of

In the blast furnace, iron is reduced and melted and the most common product is liquid iron called hot metal. In direct reduction, iron remains in solid state and the product is the socalled direct reduced iron (DRI). Generically, the iron ore products for ironmaking can be classified as shown in Table 1 .

Iron is the cheapest and one of the most abundant of all metals, comprising nearly 5.6% of the earth's crust and nearly all of the earth's core. Iron is primarily obtained from the minerals hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). The minerals taconite, limonite (FeO (OH)·nH 2 O) and siderite (FeCO 3) are other important sources.

How Is Iron Ore Found? Iron ores are rocks from which metallic iron can be economically extracted.Most deposits of iron ore in the world are found in rocks known as banded iron formations (BIFs). These are sedimentary rocks that have alternating layers of ironrich minerals and a finegrained silica rock called chert.
