For over 10 years, SampP Global Platts has provided robust and independent price assessments for iron ore. This video outlines the key processes that our editorial team undertake when assessing the iron ore market, including the important role of Platts Market-On-Close MOC process. For more information email IODEXspglobal.com.
Argus offers a comprehensive suite of iron ore assessments across fines and lump, seaborne and portside prices. Its two references for 62pc Fe iron ore, ICX and PCX, are benchmark indicators of the price of medium-grade iron ore fines imported to China and traded at Chinese ports, respectively. The ICX is an option for index-linked trade on both the Corex and Globalore platforms.
Argus is at the forefront of pioneering the highest levels of transparency in the index price-formation process, which has become increasingly important as the pricing system evolves. The ICX benchmark is published with a daily written rationale, as well as the industryrsquos first quantitative rationale, outlining exactly how much data, and of what type, went into the index, as well as how that data was weighted.
Argusrsquo reliable and robust price assessments are coupled with industry-leading news, monthly and quarterly market analysis and a unique monthly index data audit. This is supplemented by a downloadable Excel database of iron ore spot deals, bids and offers in an easy-to-use format, with granularity around each data point.
Prices and news are delivered daily online through the Argus Metals platform and through the flagship Argus Ferrous Markets report, which offers a holistic view of global ferrous markets. For the Asia-based market observer Argus also produces the Ferrous Midday intra-day update and the Ferrous Bulletin end-of-day Asia market wrap.
Steel is the world39s most popular construction material because of its unique combination of durability, workability, and cost. It39s an iron alloy that contains 0.2-2 carbon by weight.
According to the World Steel Association, some of the largest steel-producing countries are China, India, Japan, and the U.S. China accounts for roughly 50 of this production. The world39s largest steel producers include ArcelorMittal, ChinaBaowu Group, Nippon Steel Corporation, and HBIS Group.
Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century. Modern methods, however, are still based on the same premise as the original Bessemer Process, which uses oxygen to lower the carbon content in iron.
Today, steel production makes use of recycled materials as well as traditional raw materials, such as iron ore, coal, and limestone. Two processes, basic oxygen steelmaking BOS and electric arc furnaces EAF, account for virtually all steel production.
Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten ironalso referred to as hot metalstill contains 4-4.5 carbon and other impurities that make it brittle.
Primary steelmaking has two methods BOS Basic Oxygen Furnace and the more modern EAF Electric Arc Furnace methods. The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5.
Oct 26, 2020nbsp018332Iron ore beneficiation is a multi-stage process that raw iron ore undergoes to purify it prior to the process of smelting, which involves melting the ore to remove the metal content.The process of iron ore beneficiation has two complementary goals and these define the methods used to refine it. The iron content of the ore needs to be increased and gangue, which is native rock and minerals of ...
Secondary steelmaking involves treating the molten steel produced from both BOS and EAF routes to adjust the steel composition. This is done by adding or removing certain elements andor manipulating the temperature and production environment. Depending on the types of steel required, the following secondary steelmaking processes can be used
Continuous casting sees the molten steel castinto a cooled mold, causing a thin steel shell to solidify. The shell strand is withdrawn using guided rolls, then it39s fully cooled and solidified. Next, the strand is cut depending on applicationslabs for flat products plate and strip, blooms for sections beams, billets for long products wires, or thin strips.
In primary forming, the steel that is cast is then formed into various shapes, often by hot rolling, a process that eliminates cast defects and achieves the required shape and surface quality. Hot rolled products are divided into flat products, long products, seamless tubes, and specialty products.

Fastmarkets MB nbsphas produced independent assessments of non-ferrous metal prices, steel prices and scrap prices for many decades since it was established in 1913. These non-ferrous and ferrous metal prices and scrap prices are used widely. Producers, consumers and trading companies take Fastmarkets MB prices as the basis to settle contracts with their counterparties. Companies and banks employ them to value inventories or ores, and to evaluate projects and opportunities. Governments consider them when they calculate royalties and tariffs.
Fastmarkets MBnbspassesses prices in a wide variety of markets, with a number of different terms and in different currencies, at varying frequencies. Fastmarkets MBs pricing develops with markets. In 2011, we introduced more remnimbi-based pricing, index pricing and daily pricing.nbspFor people that use or are interested in the prices to understand the methods that govern their assessment and publication, an overview follows.
