From the experimental results, the present work has shown that the magnetic separation of hematite and limonite fines from iron ores can be considerably improved by selectively aggregating the fines through the hydrophobic flocculation induced by sodium oleate, kerosene and a sufficient kinetic energy input.

Magnetite vs Hematite Magnetite and hematite are minerals of iron. Both have iron in different oxidation states, and they are in the forms of iron oxides. Magnetite Magnetite is an iron oxide with the chemical formula Fe3O4.

Limonite has been known to form pseudomorphs after other minerals such as pyrite, meaning that the chemical weathering transforms the crystal of pyrite into limonite but keeps the external shape of the pyrite crystal. It has also been formed from other iron oxides, hematite and magnetite; the carbonate siderite and iron rich silicates like some ...
