Three different methods for smelting treatment of stainless steel dust

Stone coal was successfully used to synergistically treat stainless steel slag (SSS) to recover both chromium (Cr) and vanadium (V). The alloy with a Cr grade of 70.84% and a V grade of 2.36% can be obtained by keeping SSS and stone coal at a ratio of 50 : 31 at 1600 °C for 120 min. The corresponding recovery rates of Cr and V are as high as 99.51% and 81.25%, respectively. And the content of Cr2O3 in reduced slag is only 0.49%. It thus provides a new idea for the co-processing application of two solid wastes: SSS and stone coal in increasing economic potential and solving environmental issues.
