Conclusions
Increasing the degree of metallization of an iron ore concentrate from 0 to 80% decreases the ER of a mixture of the concentrate and carbon in the temperature range 600–750°C by a factor of about 200. A considerable influence on the ER of mixtures of the concentrate and carbon is exerted by temperature: On heating from 20 to 900°C their ER falls by almost two orders. The relative influence of pressing pressure on ER in the range 0–80 MPa is negligible. The results obtained can be utilized when choosing the parameters of an induction unit for the reduction heating of an ore-carbon mixture.
