Chromite Market - Global Industry Analysis and Forecast ...

Chromite is considered the commercial ore mineral of chromium, which is primarily found in ultramafic rocks such as peridotite, dunite, pyroxenite. It is also majorly found in altered derivatives such as serpentinite. Chromite deposit can be divided into two main types: stratiform or layered deposits and podiform or alpine type chromite deposit.

Magmatic Deposits / Prospecting Guidelines

Stratiform chromite deposits consist of laterally persistent chromite-rich layers (a few mm to several m thick) alternating with silicate layers. The silicate layers include ultramafic and mafic rocks such as dunite, peridotite, pyroxenite and a variety of others, less commonly gabbroic rocks.
