The specific iron content of the direct reduced iron is a function of the iron content of the iron ore. Depending on the quality of the raw ore, direct-reduced contains about 90 to 94 percent iron, which is equivalent to pig iron from a blast furnace. The high-iron-content DRI products are excellent feedstocks for the electric furnaces used by ...
Magnetite and hematite concentrates are the two main raw materials for oxidized pellet production. Magnetite concentrates have more predominance due to the heat release by oxidation during roasting and may reduce energy consumption (Jiang et al., 2008; Li et al., 2009). However, with the continuous consumption of iron resources …
