Mineral processing - Wikipedia

Concentration. There are a number of ways to increase the concentration of the wanted minerals: in any particular case the method chosen will depend on the relative physical and surface chemical properties of the mineral and the gangue. Concentration is defined as the number of moles of a solute in a volume of the solution.

Magnetite - an overview | ScienceDirect Topics

Magnetite is widely distributed usually with octahedral, or spherical, morphology, in igneous and metamorphic rocks. Magnetite is also found in limestones, in fumerolic deposits, and in living forms. For the latter the mineral plays some very important role, which we highlight in Section 8.04.3.3.2.
