Roasting | Article about roasting by The Free Dictionary

The temperature to which the ore is heated depends on the specific ore and on the purpose of roasting. Iron ore can be subjected to a magnetizing roast, which is usually reductive and converts iron oxides into the magnetic form for subsequent enrichment; this process is carried out in reverberatory kilns, shaft furnaces, or fluidized bed furnaces.

Hurstwic: Iron Production in the Viking Age

In some regions (particularly Sweden), iron ore, rather than bog iron, was the raw material for smelting. The ore was in the form of "red earth" (rauði), a powdery ocher. Regardless of the source, the raw materials were usually roasted to drive off moisture before being smelted.
