Understanding the high-grade iron ore market

Iron ore lump and sinter fines are examples of DSOs, which are mined predominantly from areas such as Australia's Pilbara and Brazil's Carajas regions, where geological processes have led to iron content levels of between 55% and 65%. These ore types require little processing beyond crushing and screening before being 'directly-shipped ...

Beneficiation of Iron Ores – IspatGuru

Beneficiation of Iron Ores. Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total ...
