Abstract: For exploring a efficient way to separate and recycle the chromium metallic resources in stainless steel dust，laboratory research by adding carbon, ferrosilicon and aluminum as reductants to stainless steel dust pellets were carried out. The results show that when only using carbon as reductant, the separation of alloy and slag in the reduction products is good at nC∶nO=1.0, and chromium content in slag develops to its minimum at slag basicity of 1.17. The recovery ratio of chromium reach as high as 96.39 % and residual mass fraction of chromium in the slag was reduced to 0.48 % by adding ferrosilicon on the basis of the dust with carbon. The recovery ratio of chromium was enhanced to 93.36 % when adding carbon and aluminum to dust.

Key words: stainless steel dust, chromium, separating condition, recovery ratio
