Characterisation and Pre-concentration of Chromite

2013-12-24  Chromite: Chromite occurs as euhedral to subhedral crystal grains, rarely angular and elongated grains are also noticed. Occasionally chromite grains were fractured. Chromite is more enriched in Fe than normal as alternation product from chromite. Rarely the alteration of chromite leads to box-work type texture (Fig.4e).
