Magnetite Concentration Methods

Elimination of Impurities . The objectionable elements occurring with magnetite which are wholely or partially eliminated by magnetic concentration, are, in the order of their importance, phosphorus as apatite, sulphur as pyrite, etc., and titanium as menaccanite or ilmenite. Apatite (calcium phosphate, sp. gr. 3.18 to 3.25) is usually

Lodestone: Definition And Magnetic Properties | Science …

Regular magnetite is not formed magnetic, and in fact, most magnetite cannot be magnetized at all. In order for magnetite to become magnetized, it must have a certain crystal structure and chemical composition. Lodestone is largely formed of magnetite, but it also has inclusions of maghemite (oxidized magnetite) and other metal ion impurities.

Iron ore - Wikipedia

Magnetite is magnetic, and hence easily separated from the gangue minerals and capable of producing a high-grade concentrate with very low levels of impurities. The grain size of the magnetite and its degree of commingling with the silica groundmass determine the grind size to which the rock must be comminuted to enable efficient magnetic separation to provide a high purity magnetite concentrate.

Razorback Iron Project | Magnetite Mines

When compared to haematite DSO, magnetite concentrates contain much lower levels of impurities, such as phosphorous, sulphur and aluminium. Iron ore concentrates derived from magnetite are a premium product and attract higher prices from steelmakers. Sample of high grade concentrate produced from Razorback ore

Sources of Magnetite Black Sand for MEOW PWT Ormus …

The color of magnetite sand ranges from gray to dark gray or dark tan to almost black in color, although the presence of "impurities" (some of which are quite desirable when using magnetite for the purposes which we have been discussing here) may change that color a bit toward charcoal or gray-black.

Magnetite: South Australia’s potential

Magnetite ore beneficiation circuits are optimised to a grind size that achieves optimal concentrate specifications (i.e. minimal impurities) for the least amount of power input (i.e. cost). Select South Australian magnetite ores are typically relatively soft when compared with ores from other Australian sources and (will) require less power inputs to achieve market specifications.

The influence of specific impurities on the nucleation and ...

The influence of traces of specifically added impurity oxides on the reduction behavior of hematite to magnetite has been investigated. Oxides of Al, Ca, Mg, or Si have a direct influence on the nucleation and growth of the magnetite. To distinguish between these nucleation and growth phenomena on the basis of the reduction rate, the nucleation model of Avrami-Erofeyev has been used.
