Iron ore consumption data are available for the United States, but not for the rest of the world. Because almost all iron ore is consumed in blast furnaces, the product of the blast furnace, pig iron, is used as the indicator of iron ore consumption. Iron ore consumption, as well as production, is concentrated in a …
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
energy consumption for iron ore efficient A review of energy use and energy efficient technologies . Based on the International Energy Agency (IEA)s statistical data published in 2012, the iron and steel industry has the technical potential to reduce its energy consumption by approximately 20% of the current total energy consumption of the sector, by applying BAT, and over 65% of this ...
May 10, 2012· Iron is the world's most commonly used metal - steel, of which iron ore is the key ingredient, representing almost 95% of all metal used per year. It is used primarily in structural engineering applications and in maritime purposes, automobiles, and general industrial applications (machinery). Iron-rich rocks are common worldwide, but ore-grade commercial mining operations are …
Iron processing Britannica.com. Iron processing, use of a smelting process to turn the ore into a form from which . on oxygen steelmaking converters using coal as a source of additional energy, For this purpose, a traveling-grate machine is used, and the burning of fine
Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and Mexico.
The use of recycling in the manufacturing process of these metals has been a main driver of improvements in energy efficiency within the industry. Primary production, in which steel is made from iron ore and aluminum from bauxite ore, is energy intensive.
Smelting reduction processes are the latest development in pig iron production. These processes combine the gasification of coal with the melt reduction of iron ore. Energy intensity of smelting reduction is lower than that of blast furnace, as the for coke production is not needed and the need for ore preparation is reduced.
Jan 01, 2013· Iron ore stockpiles increase at China's ports_Energy… Stockpiles of iron ore increased at 25 major Chinese ports during the week ending on Nov 5, according to Xinhua's latest iron ore price report, which was released on … »More detailed
Energy and Environmental Profile of the U.S. Mining Industry • Agglomerated - The development of techniques of mining and concentrating taconite led to the introduction of the iron-ore pellet. Pellets are comprised of ore that has been agglomerated into balls. The pellet is the major form of introducing iron into the steel-making blast furnace.
Today, China produces half of the world's steel, some two million tonnes per day. It imports 75 million tonnes of iron ore a month and accounts for two thirds of seaborne demand. On the supply side, Australia is the largest exporter of iron ore with 2014 exports anticipated to reach 650 million tonnes.

In Fig. 2(a) and (b) specific energy, water consumption and CO 2 emission data in respect of iron ore production is presented. The data presented is an average of iron ore mining operations from India, Australia, Brazil and Canada.
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.
