  • Safe carriage of Iron ore other iron concentrates in bulk

    Fines: small screenings of ore (less than 6mm). Fines may be sintered to form large particles, lumps or masses by heating the material to below its melting point with another material ( limestone or coke breeze) until its particles adhere together. Fines may also be pelletised to form round pellets of ore; Lump: ore of larger pieces (10mm ~ 40mm); Concentrate: ore that has .

  • Iron Ore Pelletizing Process: An Overview

    The idea of rolling moist fine ore in a drum to form balls and then drying and firing it was first patented by A. G. Andersson in Sweden in 1912. Further development was performed to bring the idea to reality. In 1943, E. W. Davies and coworkers demonstrated the process using an experimental shaft furnace. Commercial operation started in the 1950s in Sweden using verticalshaftkilns for ...

  • Understanding the highgrade 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 'directlyshipped' to customers. Iron ore concentrates are ores that ...
