  • Mineral Processing Introduction - MetSolve Labs

    The general focus of this document will be on metaliferrous ores represented by run-of-mine material described in category 3 above. An exception to the above discussion of mineral processing arises when the valuable component of the ore is extracted directly by chemical methods.

  • Ore - Wikipedia

    An ore deposit is an accumulation of ore. This is distinct from a mineral resource as defined by the mineral resource classification criteria.

  • Chromite - Wikipedia

    Chromite is an iron chromium oxide: FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.Magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4); substitution of aluminium occurs leading to hercynite (FeAl 2 O 4).

  • Nickel processing | Britannica

    Nickel processing: Nickel processing, preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties.
