Iron ore reduction in a continuously ... SpringerLink
The reduction behavior under continuous operation is influenced by both the residence time of the iron ore particles and the reduction kinetics, which is obtained by batch tests. In a mathematical model for such a process, the effect of both phenomena has to be considered.

Carbothermal Reduction of Iron Ore in Its Concentrate ...
Takyu et al. tried to understand the reduction mechanism of iron ore and carbon composite by volatile matters in biomass char at low temperature. The iron ore and carbon composite were heated at a constant rate to 1473 K, and the CO and CO 2 concentrations in waste gases were analyzed by an infrared absorption analyzer. It was found that the reduction degree at 1100 K increased with the .

Chinese iron ore imports predicted to plummet as property ...
Mr Murray said importers would mainly feel the reduction in iron ore demand as most Chinese miners were Stateowned and the country wanted to maintain a degree of selfsufficiency. Fortescue Metals Group chief operating officer Greg Lilleyman said he did not see a big reduction in Australia's iron ore exports to China over the next decade.

The reduction of the ore. At the high temperature at the bottom of the furnace, carbon dioxide reacts with carbon to produce carbon monoxide. It is the carbon monoxide which is the main reducing agent in the furnace. In the hotter parts of the furnace, the carbon itself also acts as a reducing agent.
