Stainless steel dust has been generated in stainless steel production using electric furnace and AOD/VOD furnace, which contains a large amount of valuable metal such as iron, chromium and nickel.1,2) Furthermore, stainless steel dust is classified as a hazardous industrial waste due to bearing large amounts of chromium.3) Therefore, it is of great significance to recycle valuable metals in stainless steel dust with high efficiency. Up to now, many processes have been developed for recycling chromium and nickel in stainless steel dust, for example, INMETCO, Fastmet/Fastmelt and OXYCUP et al. In INMETCO process,4,5) recovery ratio of iron, chromium and nickel are about 95%, 86% and 95%, respectively and chromium content in melt metal is about 15.2% after final reduction. In this process, stainless steel dust is not used alone, iron containing materials such as scale and mud are used together. Fastmet/Fastmelt process is very similar to INMETCO, but chromium recovery rate is low.6) OXYCUP process produces a hot metal included chromium by using coke, resulting in a high coke ratio, a high amount of slag and a high Si content in hot metal.7) Above mentioned Separation of Metal Nugget from Self-reduced Product of Coal Composite Stainless Steel Dust Briquette
