Chromium (Cr) [Z = 24]
The chrome-spinels are preserved in the in-situ deposit because of their high resistance to weathering. As a result of the removal of Mg and Si from the ultramafics, the chromite is enriched in lateritic soils by a factor ranging from 2 to more than 10. ... Genesis of low-grade chromite ore deposits in lateritic soils from the Philippines. In ...
