  • Rate-determining steps for reduction in magnetite-coal pellets☆

    2002年11月1日  In direct-reduction processes of the FASTMET type (Jimbo et al., 1999), fine iron ore is pelletised together with a carbonaceous reductant, to yield pellets with a 2002年11月1日  Reduction in packed bed of iron ore and coal under one-dimensional heating: experimental results and modelling. Packed beds of coal and iron ore (mostly in Rate-determining steps for reduction in magnetite-coal pelletsUpgrading naturally found iron ores is accomplished by grinding the ore into fine particles so that the iron containing materials can be liberated from unwanted gangue. This REDUCTION KINETICS OF IRON ORE PELLETS AND
