In this study, the beneficiation performance of chrome from the high carbon ferrochrome slag (HCFS) was evaluated. The mineralogical characteristics of HCFS was investigated first, and then HCFS was treated by magnetic separation, gravity separation, magnetic-gravity combined separation, and gravity separation after grinding respectively, to recover the Cr2O3. Finally, the Fuerstenau upgrading curves were used to evaluate the separation performance of different separation processes. The results indicated that the gravity separation process with a proper grinding condition gave the optimum beneficiation performance. A concentrate product with 30.18% Cr2O3 grade and 22.52% recovery was obtained from the HCFS.
