##tihuan2##chrome ore is very readily reduced in solid state before it is melted, resulting in a Cr2O3 content in the slag of 1.5 – 4.0 percent. Also of significance is the complete separation of metal and slag during tapping and casting due to the low viscosity of the slag [1, 5], thus the losses from this part of the operation is very low.
