AMIS0557 Cr2O3 44.1% Norite & Feldspathic Pyroxenite South Africa

Origin of Material

The chromitite layers within the Critical Zone occur as three stratigraphically delineated groups. The Lower Group ("LG") consists of seven chromitite layers hosted within a feldsphatic pyroxenite. Four chromitite layers contained within a norite and feldspathic pyroxenite sequence constituting the Middle Group ("MG") which is situated immediately between the Lower Group and the Upper.


Approximate Mineral and Chemical Composition

This material I a metallurgical concentrate mixture of MG1/MG2 wit approximate concentration of 44% for Cr2O3.
