What Are the Main Uses of Iron Ore?

4/11/2020· Iron ore are the rocks or minerals by which metallic iron is derived. Iron ores that carry a high quantity of hermatite or magnetite can be fed directly into blast furnaces in the iron production industry. The business of mining iron ore is a high volume, low margin industry because of the low value of iron.

Why is hematite used over magnetite? Magnetite has more

Magnetite ore is mined in the United States. A significant mining site in Michigan is the Marquette Range. This deposit was discovered in 1844, and ore was first mined there in 1848. The hard iron ore on this range consists of nearly pure masses of hematite and magnetite.

Geology, Prospecting and Exploration for Iron Ore

4/9/2015· The airborne magnetometer is the primary geological tool used in the search for iron ores and iron bearing materials in large areas. The method of conducting an airborne magnetic survey is to install a flux gate or proton precision magnetometer in an airplane which traverses the target area at a fixed altitude and along predetermined flight lines.

Iron processing Ores Britannica

Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used.

Not All Iron Is Magnetic (Magnetic Elements)

7/3/2019· Most people think of iron as a magnetic material. Iron is ferromagnetic (attracted to magnets), but only within a certain temperature range and other specific conditions. Iron is magnetic in its α form. The α form occurs below a special temperature called the Curie point, which is 770 °C. Iron is paramagnetic above this temperature and only weakly attracted to a magnetic field.
