Abstract: According to the resource characteristics of vanadium and chromium sludge, the direct alloying technology of chromium sludge and the clean separation technology of vanadium and chromium by alkaline liquid phase oxidation of chromium sludge have been developed in this study. The research shows that the average recovery of vanadium and chromium reaches 90% and 80% respectively, this combined process produces qualified HRB400E steel, obtains qualified sodium vanadate and sodium chromate products, and realizes efficient utilization of valuable elements in vanadium and chromium sludge.

Keywords: chromium sludge; vanadium; chromium; resource utilization

鉻是釩鈦磁鐵礦的伴生元素,在現(xiàn)有釩渣鈉化焙燒提釩工藝中,有10%~20%的伴生鉻與釩同步浸出至液相,銨鹽沉釩后,浸出的鉻及未能回收的釩留在沉釩廢水中,它以Cr6+的形式存在。(剩余2309字)
