The resulting non-conductive and non-magnetic product contains 77.8% (52.8% Cr2O3) chromite and 20.4% zircon. Further separation is difficult because chromite and zircon both are heavy minerals and non magnetic and non conducting minerals. The other method flotation may be the choice to separate chromite from zircon.
