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 indices for the key price-affecting chemical components of iron ore ironjan 07, 2021 after advancing a solid 80% last year, iron ore prices are trending above $160 per ton in 2021. It is worth mentioning that china has initiated a massive infrastructure stimulus to recover from
availability of cheaper and superior iron ore pellets from foreign sources and to the decline in domestic steel consumption. the decreased demand had a dramatic influence on the iron ore industry, as shown by the production stoppage of two of eight pelletizing plants most of irans iron ore is low grade and needs to be converted to pellets to be used to make steel. It is targeting annual steel output of million tonnes by 2025, up from about million.
descriptions have included re-oxidised iron fines, iron fines iron ore pellet chips, oxide fines, pond fines, sludge fines, remets, clarifier slush and dust, spent iron fines and lodos. other similar cargoes include dri in the description, but are offered on the basis that they are not dri and therefore do not need to be carried in jul 10, 2017 the iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. however, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. the fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. this chapter shows the status of the pelletizing process
