Chinas insatiable demand for steel combined with a slow recovery in Brazilian supply after a series of outage events has lifted the price of iron ore to a six-year high of 130 a ton, but that could be as good as it gets.
Mobile plants consist of portable shaft mixers are designed to be moveable and thus are installed on towable chassis with wheels for maximum mobility and quick setup. Mobile betching plants are perfect for temporary construction sites or construction projects where the equipment would only be needed for specific and brief portions of the projects. Mobile concrete equipment can be easily installed and dismantled and as such require very minimal preparation or set up before use.

Iron Ore Mineralogy, Processing and Environmental Issues summarizes recent, key research on the characterization of iron ores, including important topics such as beneficiation separation and refining, agglomeration e.g., production of pellets or powders, blast furnace technology for smelting, and environmental issues relating to its ...
In 2018, demand for iron ore pellets in the U.S. benefitted from improved steel production that was driven by strong economic growth, high government-led fiscal stimulus, and strong business confidence. In 2019, demand for iron ore pellets in the country witnessed moderate growth due to steady growth in steel production.
The primary end-use industries of steel include construction and automotive industries. These industries play a major role in indirectly shaping the iron ore pellet demand as it is one of the primary raw materials used for steel manufacturing. Until 2020, the global construction sector witnessed strong growth that resulted in rising crude steel production, especially in China and other Asian countries, like India.
In the first half of 2020, due to the COVID-19 pandemic, government imposed restrictions in most of the construction activities severely hindered the steel production. However, according to the World Steel Association, the construction sector is likely to gain a major boost in the second half of 2020 in various regions due to government stimulus plans. Moreover, the focus of the governments and international institutions is gradually moving from emergency liquidity provision to economic recovery and support for production, infrastructure, and industry.
Blast furnace BF pellets dominated the market for iron ore pellets in 2019 with a revenue share of 54.4 in 2019. It is a lower grade product when compared to iron pellets used in Direct Reduced DR method, and therefore has a lower cost compared to its counterpart. Blast furnace method is usually found in integrated steel plants. Lower cost of these iron ore pellets, coupled with the abundance of integrated steel plants found in developed economies, is the primary factor boosting the growth of the BF segment.
The direct reduced segment is predicted to exhibit the highest CAGR of 3.8 in terms of revenue from 2020 to 2027 owing to its rising demand in emerging economies of Asia Pacific. The operating costs as well as initial capital investments for direct reduction plants are lower than integrated steel plants, and therefore these plants are becoming more popular in developing economies, like India.

The worlds most reliable and productive direct reduction technology
The shaft furnace is where iron ore is converted to metallic. Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore reduction by counterflowing gases that have a high H and CO content. These gases react with the iron oxide in the iron ore and convert it to metallic iron, leaving HO and CO.
MIDREX Plants can be switched from one DRI form to another with no disruption of product flow CDRI to HBI, CDRI to hot DRI HDRI, or HDRI to HBI. Product can be produced simultaneously in any combination.
Cold DRI CDR DRI that is cooled prior to discharge. This product is mainly used in EAF applications and has a tendency to re-oxidize in wet environments if not properly handled and stored.
Hot Briquetted Iron HBI A DRI product hot discharged from the MIDREX Shaft Furnace into a roller-type press that molds the reduced material into dense pillow-shaped briquettes. This product is used in EAFs, blast furnaces and BOFs.
Hot DRI HDRI This product is like CDRI physically yet contains heat from the reduction process to help make EAF operations more efficient and productive.

Oct 23, 2020nbsp018332Iron ore remains the most bullish commodity of the year, with prices fueled by Chinese demand and supply disruptions in Brazil, along with bullish sentiment. But prices are expected to come down because Brazilian exports have begun to recover, and have reached their highest level since the Brumadinho dam disaster in 2019.
