Direct-Reduced Iron - an overview |

Tests to reduce fine iron ore were carried out using a pilot plant (2 tons/h) in Minnesota, USA in 1965. The DRI made from iron ore reduced by using coal as the reducing agent is not suitable for use in EAFs due to the large amount of slag and high sulfur content. As a result, the coal-based direct reduction process is utilized today mainly for
