Before roasting, the raw materials are crushed, screened, blended, and mixed, although the crushing step can be omitted if the raw materials are sufficiently fine. Fig. 10 shows the typical process of magnetic separation after reduction roasting of low-grade hematite or goethite iron ore tailings containing clay.

Shortage of raw materials could limit DRI growth. Unlike in the production of blast-furnace pig iron, iron ore remains solid throughout the DRI-production process, which makes it difficult to remove impurities (Exhibit 2). As a result, the quality of the DRI is closely related to the quality of iron ore inputs.
