Ore Dressing Methods
An ore that is self-fluxing may be of lower grade for direct smelting than one that requires the addition of a large amount of barren flux. On the other hand, a low-grade ore sometimes may be profitably mined and shipped direct because it is high in silica, iron, or lime, or some other fluxing material required by the smelter.
