Abstract Scope The metallurgical sintering method was employed to process chromium slag (CS) which contains a significant fraction of a leachable Cr(VI). And CS was added into the sinter mixtures with mass fraction of 2%, 4%, 8%, and 10%. The effects of CS on physical strength, metallurgical properties of sinter, and Cr(VI) concentration in sinter were studied. The results showed that the shattering index, tumble index both tend to first increased and then decreased with increasing addition of CS. The physical strength of sinter reached the best when the addition ratio of chromium slag was 2%. With the addition of CS increased from 0% to 10%, the reducibility index of sinter increased from 78.36% to 82.26%, whereas the low temperature reduction degradation index (RDI+3.15mm) decreased from 64.89% to 58.35%. The Cr(VI) concentration in sinters increased from 9.76 to 21.61 μg•g-1, and much lower than Cr(VI) concentration in initial chromium slag (1600 μg•g-1).
