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.
China is reportedly planning to build at least two ‘globally significant overseas iron ore mines’ by the year 2025 to boost supply. The move is part of the country’s plans to boost the metal’s supply and increase its price capacity, reported Reuters citing the Ministry of Industry and Information Technology (MIIT) According to a five year plan for the steel sector published by the.

Fresh BIF. These zones have been found to be amenable to producing iron ore products including DSO lump and sinter fines from the duricrust, and concentrate from the saprolite. Mineral resources sufficient to support commercial production of such iron ore products were defined by an intensive exploration program in 2010.
Note that it is the material in between these two iron ore type end members that can prove the most problematic. In a West African context this material is typically called Saprolite in the Brazilian context this is Itabirite, and the Brazilian industry has very successfully developed flowsheets for this material using combinations of gravity.
