chromite from laterite ore
Genesis of Low-Grade Chromite Ore Deposits in Lateritic ...
These mixed soils often occur as transported soils above non-ultramafic rocks. The abundance of chromite and the content of magnetite, ilmenite and rutile in the limonitic laterite vary considerably according to the occurrence of the accessory opaque minerals of the different types of ultramafics and to local weathering conditions.

The mineralogy of the transported Fe-Ni-Cr-laterite ore bodies from the Edessa area in Northern Greece was studied. The special emphasis was on the textural features and chemistry of chromite. The chromite was residually inherited in laterites from weathered ultramafic rocks and it displays zonation. Three main zones were optically distinguished: an inner chromite zone, an intermediate ...

Chromite: from the mineral to the commodity
2015-6-8 and trivalent metal ions, respectively. Four types of chromite ore deposits occur as either lode or secondary deposits. Lode chromite ore deposits comprise stratiform and podiform deposits, whereas secondary chromite ore deposits comprise laterite and placer deposits. Chromite is an important industrial mineral used in the refractory industry.
