Quality requirements of iron ore for iron production
However, the gangue minerals from the ferrous materials will partition either to the molten slag, if not reduced, or to the hot metal, if reduced, and are thus expected to impact on the chemistry and physicochemical properties of the BF slag and the chemistry and quality of the resultant hot metal.

Crushing and Grinding Wet & Sticky Ore
A washing section is a "must" in all operations handling wet, sticky ore. This facilitates ore handling, crushing, and also affords a means for separation of primary slimes and increasing grinding capacity. These slimes usually contain the bulk of the soluble salts and in many cases this fraction should be treated separately or even ...
