A novel reduction reaction for extracting Cr 2 O 3 from chromite ores is demonstrated by excluding the formation of carcinogenic chromate (Cr 6) intermediates.We have investigated in detail the underpinning high-temperature reduction reaction FeCr 2 O 4 Na 2 CO 3 2CFeNa 2 Cr 2 O 4 3CO (g), which defines the process chemistry for the formation of
Lower quality chromite - such as that reclaimed from other industrial processes - does not have the same levels of thermomechanical robustness as freshly mined and milled chrome sand. It is likely that sintering will occur during the casting process if low quality chrome sand is used, thereby producing an inferior final product(6).
