Genesis of Low-Grade Chromite Ore Deposits in Lateritic
As a result of the removal of Mg and Si from the ultramafics, chromite has been enriched in the lateritic soils by a factor ranging from 2 to more than 10. In some areas, soils of different ultramafic rocks are mixed due to alluvial processes which can cause further enrichments of chromite. These mixed soils often occur as transported soils ...
