Jan 10, 2022 When calcined at low temperature, the dehydration of chromite turns from dark brown to blue-black. At high temperatures, chromite reacts with soda ash or sodium peroxide to convert Cr3 + into Cr6 +. Understanding the mineral properties of chromite is the prerequisite for beneficiation. A general chromite ore mining process consists of two sections:
