713  Production of magnetite concentrate
  The production of magnetite concentrate is the physical transformation of magnetite ore (ore containing Fe3O4 that has a key property of ferrimagnetism) to produce saleable magnetite (Fe3O4) concentrate that:
 (a) has a concentration of iron (Fe) equal to or greater than 60% of the concentrate on a dry weight basis; and
 (b) has a particle size of less than 75 microns for at least 80% of the concentrate.
Note: Ferrimagnetism is ions of iron (Fe2+ and Fe3+) spontaneously aligning in the sublattice of a crystalline solid to produce a net magnetic moment that is observed as permanent magnetisation of the solid at normal room temperature.
