Chromite is an iron chromium oxide : FeCrO. It is an oxide mineral belonging to the spinel group . Magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCrO); substitution of aluminium occurs leading to hercynite (FeAlO). It is by far the most industrially important mineral for the production of metallic chromium, used as an alloying ...

This paper reviews the major deposits of lowergrade chromite in the world, and a wide variety of methods used for the recovery of chromium from them. Gangue materials in more coarsely sized ores can be separated by gravity means, whereas flotation techniques are required for finergrained materials. However, unless there is considerable iron in the ores, physical means cannot increase the Cr ...
A syngenetic mineral deposit is a deposit which formed at the same time as the rocks that enclose it. Magmatic deposits are syngenetic in that the ore minerals crystallize from the same liquid that produces the silicate minerals which form the bulk of the intrusive .
In the above picture, the known gold deposit the primary indicator minerals are fine grained arsenopyrite and pyrrhotite. In this drill core there is a nicely mineralized quartz vein with both those indicators as well as the common pyrite. This peice of core did have high grade gold speckled in amongst the arsenopyrite.
ABSTRACTMineral and morphological characteristics of chromite ore strongly affect the separation efficiency while upgrading the lowgrade deposits. Usually, chromite ore enrichment is carried out by using gravity separation due to highconcentration criterion between chromite and other minerals. However, chromite ore from Sukinda region, India, is a typical ore body with high iron content in ...

Chromite is the source of chromium used commercially and as an alloying element plays an important role in metallurgy. Balochistan is endowed with huge reserves of chromite. The first discovery was made at Muslim Bagh and Khanozai in district Kila Saifullah in 1901. Chromite deposits have also been discovered in the Ras Koh Range in [.]
