• Black Sand Concentrates

    Black sand concentrates are what you end up with after first processing of your gold bearing material. It is usually a combination of minerals in the iron group: Hematite, Fe3o3, with a specific gravity of, an iron mineral that is nonmagnetic and Magnetite, Fe3o4, with a specific gravity of, is magnetic.

  • Why iron ore grade is now more important than ever

    May 24, 2020 · There are two main types of iron ores – hematite and magnetite. Hematite is higher grade in the ground, while magnetite deposits are large and quite low grade – but produce very highgrade products. ... "There is a big difference between a 65 per cent ore and a 55 per cent ore – roughly three times the impurity levels," Eames explained.

  • Iron ore

    Generally most magnetite banded iron formation deposits must be ground to between 32 and 45 micrometers in order to produce a lowsilica magnetite concentrate. Magnetite concentrate grades are generally in excess of 70% iron by weight and usually are low phosphorus, low aluminium, low titanium and low silica and demand a premium price.

  • ILMENITE (Iron Titanium Oxide)

    Magnetite is also similar and easily confused with ilmenite, but ilmenite has a different crystal form and is not as strongly magnetic. It is often associated with magnetite and therefore ilmenite is a minor ore of iron as the magnetite and ilmenite are processed for their iron contents.

  • Magnetic Hematite Vs. Hematite Mineralogy Geology

    People might assume that magnetic hematite is simply "magnetized" hematite. True hematite, though ironcontaining, actually has a weak magnetic field because of the way its iron atoms are aligned. On the other hand, the mineral magnetite is highly magnetic, and many often erroneously assume it is magnetic hematite (the artificial material).
