sintering of iron ore fines

  • 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 ...
