Value-in-use Iron ore is a non-fungible commodity, and its quality varies. To help facilitate price adjustment for differences between expected and delivered product specifications, PRAs have developed value-in-use (VIU) indices for the key price-affecting chemical components of iron ore - iron…
19-09-2020· China, for example, accounts for nearly 60% of global capacity used to make iron from iron ore – the most energy-intensive step in primary steel production, with around eight-fold growth in its total steel production over the last two decades. It also accounts for just over half the world's kiln capacity in cement production.
The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Almost all iron ore is used in blast furnaces to make pig iron, which is the main material for steelmaking. Small amounts of iron ore are used in other applications such as coal wash plants and cement manufacturing.
Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and ...

10-04-2020· Iron ore is used primarily in the production of iron. Iron is used in the manufacturing of steel. Steel is the most used metal in the world by tonnage and purpose. It is used in automobiles, airplanes, beams used in the construction of buildings and thousands of other items. Iron ore are the rocks or minerals by which metallic iron is derived.
Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

Cement is the main basic ingredient of ready-mix concrete. Whether in bags or in bulk, CEMEX provides its customers with high-quality branded cement products for their construction needs. Cement is a fine powder, obtained from the calcination at 1,450°C of a mix of limestone, clay, and iron ore.
Scrap-based production (also referred to as secondary or recycled production) can be valuable in reducing energy demand and CO 2 emissions, as it is considerably less energy-intensive than primary production from iron ore. Scrap is used as the main ferrous feed in electric arc furnaces (EAFs), as well as in induction furnaces to a lesser extent.
Prices for iron ore cargoes with a 63.5% iron content for delivery into Tianjin extended losses to $180.5 a tonne, the lowest since April 19th on weak seasonal demand and as some Chinese steel producers were told to cut production. Weekly consumption for major steel products in China as of August 5th fell 2.5% to 9.86 million tonnes from a week earlier, data from Mysteel consultancy showed.
Platts Iron Ore Index assessments reflect the tradeable price of iron ore at 5.30pm Singapore/Beijing time (9.30 am GMT). The IODEX assessment is not origin specific, and takes into account ores with iron content between 60-63.5% Prior to 2012, the spot market saw Indian material traded most actively; this shifted, with Australia being the main source of spot medium grade fines material.
05-10-2016· Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
