1. Fines : Fines is chrome ore in the form of individual particles with majority of such particles measuring less than 4.00 millimetres. It is in concentrated form. This is also called as chrome concentrate.
2. Friable : Friable Ore is the form of chrome ore with majority of particles measuring more than 10.00 millimetres. It is also in non concentrated form. Friables are less naturally occurring than fines as the ore is reduced to fine particles during beneficiation process.
