Magnesiochromite: The mineral magnesiochromite …

Magnesiochromite is very similar to Chromite, and is often mistaken for it. Due to their similarity, it is very difficult to visually distinguish these two minerals. Magnesiochromite is the magnesium-dominating form in a series with Chromite, whereas Chromite is iron-dominating. Chemical Formula. MgCr2O4.

Changes in the magnetic properties of chromite ore heated ...

The increase in the magnetic properties of chromite ores after firing occurs on account of the increase in the magnetic susceptibility of the gangue from (50–120)×10 −6 to (6000–8000)×10 −6 cm 3 /g. Thus after firing of chromite ores with iron-containing additives the gangue acquires ferromagnetic properties. The magnetic susceptibility of the gangue is 50–115 times greater than chrome-spinel which permits us to use highly productive magnetic …

Chromite - Wikipedia

Chromite is a crystalline mineral composed primarily of iron oxide and chromium oxide compounds. It can be represented by the chemical formula of FeCr2O4. It is an oxide mineral belonging to the spinel group. The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite. A substitution of the element aluminium can also occur, leading to hercynite. Chromite …

Below this temperature the magnetic contributions to the fundamental spinel peaks arising from aligned spins increases as the temperature is lowered and is effectively saturated at about 20°K. At 18°K, additional sharp peaks appear at positions which cannot be indexed either on the original unit cell or on any reasonably enlarged cell. These extra reflections persist with unchanged intensities down to …
