PROCESS FOR BENEFICIATING MAGNETITE IRON ORE

The invention is illustrated in the accompanying drawing which is a schematic flow sheet of the beneficiation process. The amount of iron in taconite ore that occurs as magnetite cannot be determined chemically and, therefore, a laboratory apparatus, the Davis magnetic tube concentrator, is used to remove all of the magnetite from a finely

Besides, the separation machines are devide into the dry and wet magnetic separation. Generally, iron ore with an iron content of 35% can increase iron content by 20% after magnetic separation. Such a combined process method, the ore utilization rate can reach 90%. In the process of magnetic separation, it saves water, reduces cost and pollution.

Iron ore Wikipedia

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and

Magnetic Behavior of Natural Fe2O3 from Lhoong Iron

The mineral composition and magnetic behavior of nano-Fe 2 O 3 of iron ore from Lhoong mining area, Aceh province, were studied. The iron ore was prepared by mechanical milling method. The mineral and chemical compositions of samples were investigated by XRD and XRF analysis tests. The XRF test showed that the Lhoong iron ore contains Fe<sub>2</sub>O<sub>3</sub> (93.88%) in

Not All Iron Is Magnetic (Magnetic Elements)

7/3/2019· Iron is ferromagnetic (attracted to magnets), but only within a certain temperature range and other specific conditions. Iron is magnetic in its α form. The α form occurs below a special temperature called the Curie point, which is 770 °C. Iron is paramagnetic above this temperature and only weakly attracted to a magnetic field.
